FUNCTION AND APPLICATION

10

MIX OUT 1

2.3

Mixer output from upconverter.

11

MIX OUT 2

2.3

Mixer output from upconverter.

10 and 11 pins should be externally

equipped with tank circuit of inductor (eg

4.7 nH) and capacitor (eg 3.5 pF).

12

GND

0*

Ground for oscillator buffer amplifier and

mixer of upconverter.

Must be connected to the system ground

with minimum inductance. Ground

pattern on the board should be formed

as wide as possible.

(Track length should be kept as short as

possible.)

13

IF bypass

1.03

Bypass of IF input for upconverter.

14

IF input

1.03

This pin is IF input for upconverter

designed as double balanced mixer.

This high-impedance input should be

externally equipped with matching circuit

of inductor (eg 220 nH) and capacitor

(eg 1.5 pF).

15

OSC input

(for upconverter)

1.8

Local oscillator input for upconverter. Re-

quired for matching with register 51 Ω.

16

OSC bypass

(for upconverter)

1.8

Bypass of local oscillator input for

upconverter.

17

OSC bypass

(for down-

converter)

1.85

Bypass of local oscillator input for

downconverter.

18

OSC input

(for down-

converter)

1.85

Local oscillator input for down-

converter. Required for matching with

register 51 Ω.

19

VCC supply for

2.7 to 4.5* Supply voltage for downconverter.

for down-

It must be connected bypass capacitor

converter

(e.g 1 000 pF) to minimize ground

impedance.

20

IF output

1.45

IF output from downconverter.
