1

Vcont

0 to 3.0

-

Gain control pin of AGC amplifier.

Variable gains are available in accordance

with applied voltage.

2

N.C.

-

Non connection.

19

This pin is not connected to internal circuit.

This pin should be opened or grounded.

—

3

LO

-

Local signal input pin of I/Q demodulator.

Input frequency is 760 MHz.

4

LOb

-

Bypass pin of local signal input for I/Q

demodulator.

In the case of single local input, this pin must be

decoupled with capacitor ex. 100 to 1 000 pF.

5

GND

0

-

Ground pin of I/Q demodulator.

6

(Demod.)

This pin should be grounded with minimum

inductance.

Form the ground pattern as widely as possible to

minimize ground impeadance.

7

Qb

-

I/Q/Ib/Qb signal output pins.

8

Q

-

Each pin is an emitter follower.

9

Ib

-

Each of Ib and Qb is differential output of I and Q.

10

I

-

Recommendable load impedance is 10 to 20 kΩ.
