Fairview Microwave Inc., a supplier of on-demand microwave and RF components, introduces a new line of Single Pole Double Throw (SPDT) PIN Diode Switches that offer exceptional reliability and repeatable performance in compact and rugged coaxial packages. They are commonly used in RF, microwave and millimeter-wave test systems associated with test and measurement, communications systems, SATCOM, avionics, radar, hi-rel electronics, medical equipment, laboratory experimentation, etc. Specific applications may include signal routing between instruments and devices under test or used in switch matrix test systems that enable routing of signals where multiple tests can be automated using the same test setup. Additionally, the benefit of fast switching speed performance is critical in applications where multiple switches are being used in series, or where highly sensitive transmit and receive switching rates need to be established.

Fairview offers a comprehensive selection of 23 different models of SPDT PIN diode switches that cover frequencies ranging from 10 MHz to 67 GHz. The high isolation levels up to 80 dB ensure that unwanted signals will not leak into the desired signal path. Other critical performance features include low insertion loss as low as 1.1 dB and fast switching speed performance as low as 50 nanoseconds. Both absorptive and reflective designs are available and every model utilizes integrated TTL compatible high speed driver logic circuitry. These SPDT switches are constructed using MIL-Grade rugged coaxial packages and several models support field replaceable connectors. All models are EAR99.

Fairview’s SPDT PIN diode switches are in-stock and available today.
