Description

Interface Schematic

RF signal output for external 50Ω filtering.The use of a filter here is

optional but does provide for lower noise floor and better out-of-band

rejection.

Supply voltage for the LNA. This pin should be bypassed with a 10 pF

capacitor to ground as close to the pin as possible. The shunt induc-

tance from this pin to ground via the supply decoupling must be tuned

to match the LNA output to 50Ω at the desired operating frequency.

See pin 16.
