Evaluation Board for F2923 SP2T with Constant Impedance, K|z|

The F2923EVBI is a fully populated evaluation board which allows the customer to easily evaluate the product.

“Thru” calibration connectors are conveniently located on the eval board to simplify the calibration process prior to making any RF measurements. Each RF port (RFC, RF1 and RF2) can be connected to RFC by applying the correct control logic voltage to the V1 and V2. The Mode Control pin 19 allows the part to be configured for either 1 pin or 2 pin control.
