Amplifiers

The Company offers a line of amplifiers, including high power amplifier modules that are chassis mounted with standard connectors, offer power outputs up to 15 watts and can be easily inserted into RF and microwave communication, test and sensor systems; wideband amplifiers having more than an octave of operating frequency bandwidth (that is, where the highest frequency is twice the lowest frequency), used in military, space and commercial systems where a range of frequencies need to be processed by one subsystem; power amplifiers used to increase the power level of the signal in transmitter or high power level applications; linear driver amplifiers used in transmitters or receivers where distortion must be minimized to maintain signal fidelity; microwave and optical driver amplifiers used in fiber optic applications where wide bandwidth and high output voltage swings are required to drive optical components; low noise amplifiers used in the first stage of a receiver, where amplification with minimum distortion of an incoming signal having a low power level is required, and broadband gain blocks used throughout the receiver and transmitter sections of already fixed systems to boost signal level.

Attenuators

Attenuators are used to reduce the power of a RF, microwave or millimeterwave signal in specific controlled amounts without distorting the signal quality. The portfolio of standard attenuators is classified into two types: analog attenuators that provide control of the RF, microwave or millimeterwave signal in response to an analog direct current (DC) voltage input and can deliver continuously varying, very fine to very large levels of attenuation and digital attenuators that provide control of the RF, microwave or millimeterwave signal in response to a digital logic input and deliver preprogrammed levels of attenuation according to the digital input.

Data converters

Data converters are used to convert signals between analog and digital format. Its product line includes track-and-hold (T/H) amplifiers that convert analog sinusoidal signals to high speed digital square wave signals for baseband processing.

Dielectric Resonator Oscillator

An oscillator is a device that produces a RF, microwave or millimeterwave frequency. A dielectric resonator oscillator (DRO) is a class of oscillator in which the output frequency is mechanically stabilized over a very narrow range by a resonating dielectric material. Its DRO products are optimized for military, test equipment and industrial/medical equipment applications, and are characterized by their low phase noise, low temperature drift and robust packaging.

Frequency dividers and detectors

Frequency dividers, also called prescalers, and phase-frequency detectors are used in frequency generation circuits, or synthesizers, to help process and distribute the carrier frequency of the system. It offers a full range of frequency dividers and phase-frequency detectors. Its standard dividers and detectors include phase-frequency detectors, wideband frequency divider modules, programmable frequency dividers and frequency dividers.

Frequency multipliers

Frequency multipliers are used in frequency generation circuits, or synthesizers, to increase by a predetermined factor the carrier frequency and to help distribute it throughout the system. It offers a full range of active and passive frequency multiplier standard products, including active multipliers and passive multipliers, or frequency doublers.

High Speed Comparators

A high speed comparator is a device that constantly monitors signal levels at its inputs. The device generates a digital output signal based on the difference in amplitude of the input signal levels.

High speed digital logic products

High speed digital logic products are used to select, split, invert, route, multiply or delay high speed digital signals. High performance digital systems require these functions to route the signal throughout a digital backplane. Its high speed digital logic products can support digital signals, which propagate at speeds of 13, 26 and 40 gigabits per second (Gb/s), which makes them suitable for OC-48, OC-192 and OC-768 applications.

Interface

Interface products are used in the digital or analog control of RF, microwave, and millimeterwave integrated circuits. Its first interface product converts a serial or parallel logic input to a six bit wide complementary output, and can be used to simplify the control of digital attenuators, digital phase shifters, digital variable gain amplifiers and switch matrices.

Limiting amplifiers

Limiting amplifiers increase the gain or power of an RF, microwave, millimeterwave or digital signal, and have the feature of adding more gain or power to low level signals, and less gain or power to high level signals. Its limiting amplifier product line is optimized for fiber optic communications and features low jitter and high data rate capability.

Mixers and converters

Mixers, upconverters and downconverters are used to transform frequencies from a higher frequency input to a lower intermediate frequency, or vice versa, for easier processing of the RF, microwave or millimeterwave signal. The input signal is combined with a fixed carrier signal generated by a local oscillator (LO) to produce the higher or lower output frequency.

Modulators and demodulators

Modulators are used in radio transmitters to combine a digital information signal with an analog carrier signal generated by an LO. Demodulators are used in radio receivers to extract the digital information signal from the analog carrier signal. Its modulators and demodulators address a variety of modulation schemes and feature high linearity, low noise and wide bandwidth.

Oscillators

An oscillator produces an RF, microwave or millimeterwave frequency. The output frequency of its voltage controlled oscillators (VCOs) can be varied by an analog DC input control voltage. It offers three types of MMIC oscillators: wide band VCOs, narrow band VCOs and phase lock oscillators.

Passives

Passive product line consists of 12 fixed attenuators, which operate at frequencies up to 50 GHz. Fixed attenuators, or pads, are used to accurately reduce the power level of a signal without distorting the signal’s characteristics.

Phased lock loops

PLL integrated circuits are used in conjunction with oscillators in RF, microwave, and millimeterwave signal generation circuitry to accurately select and stabilize the frequency of transmitted and received signals. Its PLL products are designed to minimize noise, allow wide input bandwidth and provide advanced features.

Phase lock loops with integrated voltage controlled oscillators

A PLL with integrated VCO produces an RF, microwave or millimeterwave frequency. Its PLL with integrated VCO products combine a fully integrated, low noise VCO, with an advanced PLL integrated circuit.

Phase shifters

Phase shifters are used to change the phase of an RF, microwave or millimeter wave signal while providing little or no amplitude change or distortion. Analog phase shifters provide continuous phase change as a function of control voltage, often allowing over 360 degrees of phase shift and Digital phase shifters provide discrete phase shift changes with a single control voltage, often in a combination of small and large phase steps.

Power Conditioners

A power conditioner supplies DC power to an integrated circuit. Its power conditioner regulates the voltage level of a DC power supply, and removes unwanted noise and spurious products that can be detrimental to the performance of RF, microwave or millimeterwave integrated circuits.

Power detectors

Power detectors convert RF signals to DC voltages that can be measured by simple digital circuitry. These devices convert power levels from logarithmic to linear voltages.

Sensors

The Company’s sensors use RF, microwave and millimeterwave energy to detect, measure or form an image of an object. These sensor ICs integrate multiple circuit functions and are effectively subsystems on a chip.

Switches

Switches are used to route RF, microwave or millimeterwave signals from one or more input paths to one or more output paths. Control of the selected input and output signal path is achieved via digital logic input.

Synthesizers

Synthesizers generate a coherent set of RF, microwave or millimeterwave frequencies over a specified range of frequency and power. Synthesizers are generally used to generate the frequency that acts as a carrier for voice or data communication.

Transimpedance Amplifiers

Transimpedance amplifiers are used between devices, which have very different levels of impedance or resistance. Its transimpedance amplifier provides a differential output voltage that is proportional to the current at its input, and is optimized for photodiode and fiber optic data communication applications.

Variable gain amplifiers

Variable gain amplifiers (VGAs) boost the gain or power of a RF, microwave or millimeterwave signal and have the feature of allowing the user to set the gain or power at a specific level. Its variable gain amplifier MCMs utilize GaAs linear amplifiers, high performance six bit GaAs digital attenuators, and CMOS silicon drivers.

The Company competes with Avago, Analog Devices, Eudyna, Linear Technology, NEC, RFMD, Skyworks, TriQuint Semiconductor and United Monolithic Semiconductor.
