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.
