Evaluation Board for 75 Ohm SP2T Absorptive RF Switch
The F2971EVBI is a fully populated evaluation board enabling easy RF evaluation of the F2971 product.
“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 control pins as outlined in the datasheet. DC power, ground and the control voltages are applied to the pin header.
