Overview
The 40-781A-922 (PXI) and 42-781A-922 (PXIe) modules consist of two microwave changeover switches 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 have the advantage that the terminations can be removed and replaced with higher power RF loads. This also allows alternative configurations such as terminated 4-port bypass (1 termination removed) and 5-port DP3T (both terminations removed). See the datasheet for diagrams of these configurations.
The 4x-781A gives you the highest RF switching performance available within a Pickering switching system. Although designed for microwave applications, they have many uses in the RF spectrum where extremely low insertion loss and ultra high isolation are critical. They may also be used at lower frequencies where power handling to 35 W (without termination) is required.
