40-780B PXI Dual Microwave Relay
Click image to enlarge


The 40-780B-532 (PXI) and 42-780B-532 (PXIe) are dual failsafe SPDT 26.5 GHz unterminated microwave relay modules. The 40/42-780B range is available with one, two, three or four SPDT switches capable of switching frequencies up to 67 GHz in 50 Ω or 2.5 GHz in 75 Ω. Connections are made via front panel mounted high quality RF coaxial connectors, SMA or N-Type for 50 Ω and 1.6/5.6 in 75 Ω versions. Remote versions are also available which can support up to three SPDT relays in a single slot.

The remote versions, as well as occupying less panel space in the case of the triple options, allow the microwave relays to be placed closer to the UUT and RF test equipment. This can shorten the length of cables and improve system performance. Remote multiplexers are supplied with a 1.5 m interface cable.

These PXI/PXIe Microwave relay modules give you the highest RF and microwave 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 for lower frequency RF applications where power handling to 240 W is required (700 W for N-Type options).
