RF IN GROUND Function Pin Number Description RF IN 1 RF input pin. This pin requires the use of an external DC blocking capacitor chosen
for the frequency of operation. RF-OUT and DC-IN 3 RF output and bias pin. DC voltage is present on this pin; therefore a DC blocking
capacitor is necessary for proper operation. An RF choke is needed to feed DC bias
without loss of RF signal due to the bias connection, as shown in “Recommended …
