Pickering Interfaces announced a new range of PXI/PXIe microwave relay modules capable of switching the 110 GHz signals associated with demanding RF & communications applications, including emerging technologies such as automotive radar. This extension to Pickering’s family of terminated SPDT microwave switches is the first to be offered in 110 GHz, delivering the highest RF switching performance available within a Pickering switching system.

The 40-781A-92x (PXI) and 42-781A-92x (PXIe) modules consist of either a single or dual microwave changeover switch payload, capable of switching up to 110 GHz in 50 Ω. They are available with external terminations, and connections are via front panel mounted high quality SMA 1.0 connectors. Externally terminated switches offer the advantage that the user-accessible terminations can be removed and replaced with higher-power RF loads for increased signal levels. This switch topology flexibility also allows alternative configurations to alter the switching functionality, such as terminated 4-port bypass (1 termination removed) and 5-port DP3T (both terminations removed).
