Description

1

LNAOUT

Output terminal. This is the power supply terminal of the LNA. Please use

inductor(L5) to connect power supply.(Please see test circuit.)

2

VCTL

Control voltage input terminal. This terminal is set to Full band and CD

band to select.

3 LNAIN2 Input terminal of full band. The DC blocking capacitor is not required.

4 LNAIN1 Input terminal of CD band. The DC blocking capacitor is not required.

5

GND Ground terminal (0V)

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

6

IFOUT

circuit connected to this terminal. Please connect inductances C4, L9 and

power supply as shown in test circuits, since this terminal is also the

terminal of mixer power supply.

7

VLO

Power supply terminal for local amplifier. Please place L8 shown in test

circuits at very close to this terminal.

8

GND Ground terminal (0V)

9

LOIN

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

required.

10

GND Ground terminal (0V)

11

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

12

VINV Power supply terminal of the inverter circuit.

NOTE:

1) Ground terminal (5, 8, 10pin) should be connected to ground plane by multiple via holes

for good grounding.
