TERMINAL INFORMATION

No. SYMBOL FUNCTION

1 LNAIN RF input terminal of LNA. An external matching circuit is required.

2 LNACAPTerminal for the bypass capacitor of LNA. The bypass capacitor C1 asshown in test circuits, should be connected to this terminal as close aspossible.

3 GND Ground terminal(0V)

4 IFOUT

IF signal output terminal. The IF signal is output through external matchingcircuit connected to this terminal. Please connect inductances L7, L8 andpower supply as shown in test circuits, since this terminal is also theterminal of mixer power supply.

5 VLO Power supply terminal for local amplifier. Please place R1 and L10 asshown in test circuits at very close to this terminal.

6 LOIN Local signal input terminal to local amplifier. An external matching circuit isrequired.


8 MIXIN RF signal input terminal to mixer. An external matching circuit is required.


10 LNAOUT

Signal output terminal of LNA. The RF signal from LNA is output throughexternal matching circuit connected to this terminal. Please connectinductances L3, L4 and power supply as shown in test circuits, since thisterminal is also the terminal of LNA power supply.

CAUTION1) Ground terminal (No.3, 7, 9) should be connected to the ground plane as low

inductance as possible.
