Evaluation Board for High Reliability SPST Absorptive RF Switch

The F2911EVBI is a fully populated evaluation board which allows the customer to easily evaluate the F2911 RF switch. 

“Thru” calibration connectors are conveniently located on the evaluation board to simplify the calibration process prior to making any RF measurements. The RF through measurement (RF1 to RF2) can be made by applying the correct control logic voltage to the V1 control pin as outlined in the F2911 datasheet. DC power, ground and V1 control voltages are applied to the pin header. A bypass capacitor has been added to the evaluation board to achieve best performance from 1MHz to 3500MHz, as described in the applications circuit section of the datasheet.
