RF input terminal of LNA. The RF signal is input through external matching
circuit.
Terminal for the bypass capacitor of LNA. The bypass capacitor C1 shown in
application circuit, should be connected to this terminal as close as possible.
Ground terminal(0V)
IF signal output terminal. The IF signal is output though external matching
circuit’s connected to this terminal. Please connect inductance L8 and power
supply as application circuit since it is also the terminal of Mixer power supply.
Power supply terminal for local amplifier. Please connect R1 and L10 to this
terminal shown in the application circuit as close as possible.
Local signal input terminal of local amplifier. The local signal input to Local
Amplifier through external matching circuit.
Ground terminal(0V)
RF signal input terminal of Mixer. The RF signal from LNA is sent to Mixer
through matching circuit.
Ground terminal(0V)
Signal output terminal of LNA. The RF signal from LNA is output through external
matching circuit connected to this terminal. Please connect inductance L4 and
power supply shown in application circuit, since it is also the terminal of LNA
power supply.
