Trilithic manufactures 50 and 75 ohm, SPDT, SP4T, and SP8T RF Switches.
The SPDT RF Switches include latching and non-latching electronically controlled switches, covering the range of DC to 1,000 MHz, are available in a variety of configurations including a direct PCB-mountable version. The A and B ports are internally terminated when not connected to the common port. Control options include non-latching CMOS, latching and non-latching TTL, as well as direct drive. Switching time is 10 milliseconds and the rated life is over 1 million actuations. When non-latching relays are used, there is no ambiguity as to the switch state after a power failure, common is connected to port A.
The SP4T and SP8T Switches are controlled via nine conductor D-Subminiature connectors with hard-wired internal logic. A single line controls each switched port connection to the common port. TTL and CMOS compatible drivers are available. Switching time is 10 milliseconds and the rated life is over 1 million actuations. When non-latching relays are used, there is no ambiguity as to the switch state after a power failure, common is connected to port 1.
