PIN Diode Waveguide Switches Cruise E/W Bands

Fairview Microwave’s latest line of E and W-band PIN diode waveguide switches are single-pole single-throw (SPST) and single pole double-throw (SPDT) millimeter-wave waveguide switches offering an ultra-broadband frequency range with fast switching performance.  They are viable for telecommunications, test instrumentation, research and development programs and radar front ends in applications that involve general switching, receiver protection, pulse modulation, and antenna beam switching.   


Four of the components feature integrated WR10 and WR12 waveguide ports that support a UG387/U flange and cover E-band (60 to 90 GHz) and W-band (75 to 110 GHz) frequencies.  These designs employ GaAs beam-lead diodes and low-loss Fin-line technology, resulting in performance of 4 dB typical insertion loss, 25 dB of isolation, and a switching speed of less than 300 ns. Integrated TTL driver circuitry with an SMA connector control port provides ease of use.

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.


All waveguide PIN diode switch models require a dual voltage bias of ±5 Vdc and have a maximum rated CW input power level of 0.5 dBm. Rugged MIL-grade compact package configurations integrate both switch and control packaging and offer maximum performance and reliability over a full temperature range of -55°C to +85°C. For more specs and greater enlightenment, check out the waveguide PIN diode datasheets and/or call 972-649-6678.
