Fairview Microwave Inc. has released a new line of E and W-band PIN diode waveguide switches. These single-pole single-throw (SPST) and single pole double-throw (SPDT) millimeter-wave waveguide switches offer an ultra-broadband frequency range with fast switching performance. They are ideal 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.
Fairview’s four new PIN diode waveguide switches feature fully 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 utilize high-performance GaAs beam-lead diodes and low-loss Fin-line technology, resulting in exceptional performance of 4 dB typical insertion loss, 25 dB of isolation and fast switching speed of < 300 nsec. Fully integrated TTL driver circuitry with an SMA connector control port provides ease of use. All of these waveguide PIN diode switch models require a dual voltage bias of +5/-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.
“Fairview’s attractive series of millimeter-wave SPST and SPDT PIN diode switches offers desirable broadband performance that covers popular E and W-band frequencies up to 110 GHz in compact rugged packages with fully integrated WR10 and WR12 waveguide ports and innovative TTL driver circuitry. These waveguide switches usually command long lead-times, but Fairview has four different models available off-the-shelf and ready for delivery,” said Tim Galla, Product Manager.
Fairview’s new E and W-band PIN diode waveguide switches are in stock and ready for immediate shipment with no minimum order quantity.
