QuinStar Technology, Inc. specializes in producing a broad range of fully integrated and customized millimeter-wave assemblies and subsystems meeting customer-specific application requirements for digital and analog Sensor, Communications and Test applications.

35 GHz Linear Exciter With High Isolation and High Speed Switching

QuinStar has designed, produced and delivered dozens of different millimeter-wave assemblies and subsystems ranging from Miniature Transceivers and Broadband Receivers to Antenna Subsystems and Communication Front Ends.

QuinStar’s in-house oscillator, amplifier and frequency multiplier product design and manufacturing resources greatly enhance our capability to offer State-of-the-Art solutions for Rapid Prototyping and Proof of Concept Demonstration all the way through Production.

The level of integration, circuit complexity, packaging and testing provided by QuinStar are all determined by the customers’ precise needs, budget limitations and environmental constraints. In addition, customers are often able to select from a vast variety of existing generic millimeter-wave assemblies and subsystems that are fully developed and readily producible. This results in significant cost savings, quick delivery and avoidance of developmental risks.

QuinStar can develop and produce customized assemblies and subsystems from virtually any starting point in the customers’ application development cycle and on the basis of any degree of definition or specification.

W-Band Phase-Lockable Source Assembly

We can work from just a Conceptual Design or Generic Description, or convert a Functional Block Diagram or Circuit Schematic into a customized assembly or subsystem. We are also well positioned to economically manufacture an assembly or subsystem on a Build to Print basis if desired.

Some of QuinStar’s commonly produced millimeter-wave assemblies and subsystem products include:

Sensitive Receivers: QuinStar has developed a complete line of sensitive receiver front ends that operate over the 18-140 GHz frequency interval.

Phase-Lock Electronics

These receiver front ends may be used in systems ranging from EW receivers to environmental sensors and meteorological radiometers. Low-noise amplifiers produced by QuinStar allow us to offer state-of-the-art performance.

Generic Transceivers: Front ends for radars with virtually any waveform (CW, FMCW, pulsed or various other complex modulation waveforms) have been produced to meet requirements ranging from automobile collision warning systems to plasma diagnostic instruments.

76.5 GHz 3-Channel Monopulse Transceiver

QuinStar’s strength in high performance transmitter components, such as amplifiers and oscillators, greatly enhances the performance of these custom products. In addition, our significant experience allows us to deliver a cost-effective, fully compliant assembly or subsystem well matched to the application.

Antennas and other assemblies can also be integrated with these transceivers.

Antenna-Related Subsystems: QuinStar routinely provides complex antenna product assemblies consisting of a variety of antennas, polarizers, orthomode transducers and associated waveguide products integrated to achieve customer-specified performance.

Special Test and Measurement Equipment: QuinStar produces customized test and measurement equipment for special applications and/or dedicated production measurements. These include Noise/Gain Test Sets, Voltage Standard Measurement Systems and Frequency Extension Kits for Network Analyzers.

Transmitters and Sources: Sources especially suited for transmitters for communication equipment, sensors, seekers, plasma diagnostic instruments and test equipment are offered as customized products.

76.5 GHz FMCW Transceiver Assembly

These are based on QuinStar’s broad active component product line. In addition, frequency agile (sweepers), synthesized and phase-locked sources are offered.
