FUNCTION
RF input terminal of LNA. An external matching circuit is required.
Terminal for the bypass capacitor of LNA. The bypass capacitor C1 shown
in test circuits should be connected to this terminal as close as possible.
Ground terminal (0V)
IF signal output terminal. The IF signal is output through external matching
circuit connected to this terminal. Please connect inductances L7, L8 and
power supply as shown in test circuits, since this terminal is also the
terminal of mixer power supply.
Power supply terminal for local amplifier. Please place L6 shown in test
circuits at very close to this terminal.
Local signal input terminal to local amplifier. An external matching circuit is
required.
Terminal for the bypass capacitor of mixer. The bypass capacitor C4
shown in test circuits should be connected to this terminal as close as
possible.
RF signal input terminal to mixer. An external matching circuit is required.
Ground terminal (0V)
Signal output terminal of LNA. The RF signal from LNA goes out through
external matching circuit connected to this terminal. Please connect
inductances L3, L4 and power supply as shown in test circuits, since this
terminal is also the terminal of LNA power supply.
