n TERMINAL INFORMATION

No. SYMBOL

FUNCTION

1

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

2

LNACAP

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.

3

GND Ground terminal (0V)

IF signal output terminal. The IF signal is output through external matching

4

IFOUT

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.

5

VLO

Power supply terminal for local amplifier. Please place R1 and L11 shown

in test circuits at very close to this terminal.

6

LOIN

Local signal input terminal to local amplifier. An external matching circuit is

required.

Terminal for the bypass capacitor of mixer. The bypass capacitor C4

7

BPC shown in test circuits should be connected to this terminal as close as

possible.

8

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

9

GND Ground terminal (0V)

Signal output terminal of LNA. The RF signal from LNA goes out through

10

LNAOUT

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.

CAUTION

1) Ground terminal (No.3, 9) should be connected to the ground plane as close as possible.
