Commonly used in RF, microwave and millimeter-wave test systems that are associated with test and measurement, communications systems, SATCOM, avionics, radar, hi-rel electronics, medical equipment, laboratory experimentation, and so on, are Single Pole Double Thrown (SPDT) PIN Diode Switches.
Fairview Microwave Inc. has just introduced a new line of SPDTs that offer reliability and repeatable performance, all in compact and rugged coaxial package. 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. These SPDT's cover frequencies that range 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 also has available 74 other varieties of PIN diode switches in the following configurations: SPST, SP3T, SP4T, SP5T, SP6T, SP8T, SP12T, and Transfer.
