GaAs MMIC HERMETIC SMT VOLTAGE-
VARIABLE ATTENUATOR, DC - 8 GHz
5
Pin Descriptions
Pin Number
1, 8
Function
RF1, RF2
Description
This pin is DC coupled and matched to 50 Ohm. 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 - 88
Note:
External op-amp control circuit maintains imped-
ance match while attenuation is varied. Input con-
trol ranges from 0 Volts (min. attenuation) to -2.5
Volts (max. attenuation.)
