RECEIVER PRODUCTS
Broadband Detectors, Harmonic Mixers and Diplexers, Balanced Mixers, Subharmonic Mixers
While QuinStar milli-meter wave receivers are designed and manufactured for maximum performance, we offer a wide range of components to meet precise needs of your industries and applications. Our extensive product line includes broadband detectors and balanced phase detectors, harmonic mixers and diplexers, spectrum analyzer mixers and diplexers, and upconverters. We also offer balanced mixers, subharmonic mixers, and I-Q mixers. Most of our receiver products cover the frequency range of 18 – 110 GHz in several waveguide bands. But some products cover the frequency range of 18 – 170 GHz.
SOURCES & MULTIPLIERS
Gunn Oscillators, Gunn Regulators/Modulators, High Power IMPATT Diodes, Stable Millimeter Wave Sources, Phase Locked Sources, Active Frequency Multipliers, Passive Frequency Multipliers, Noise Sources, Frequency Extenders
QuinStar’s Sources & Frequency Multipliers products include passive and active frequency multipliers extending to 110 GHz. The active frequency multiplier features amplification with integral filter. This state-of-the-art active multiplier is for frequency multiplication and amplification over 8 – 110 GHz. The passive model requires no external bias and features full waveguide bandwidth and low conversion loss.
