HMC346C8

GaAs MMIC SMT VOLTAGE-

VARIABLE ATTENUATOR, DC - 8 GHz

Pin Number

1, 8

Function

RF1, RF2

Description

This pin is DC coupled and matched to 50 Ohms. Blocking

capacitors are required if RF line potential is not equal to 0V.

Interface Schematic

2, 7

GND

This pin must be DC grounded.

3, 6

V2, V1

Control Input (Master).

4

I

Control Input (Slave).

5

O

This pin must have an external 500 Ohm resistor to ground.

Single-Line Control Driver

5 - 82

Note:

External op-amp control circuit maintains imped-

ance match while attenuation is varied. Input control

ranges from 0 Volts (min. attenuation) to -2.5 Volts

(max. attenuation.)
