Functional Schematic

Description

M/A-COM’s AT-263-PIN is a GaAs FET 5-bit digital

attenuator with a 1 dB minimum step size and 31 dB

total attenuation. This attenuator and integral TTL

driver is in a hermetically sealed ceramic 16-lead

surface mount package. The AT-263-PIN is ideally

suited for use where accuracy, fast switching, very

low power consumption and low intermodulation

products are required. Typical applications include

dynamic range setting in precision receiver circuits

and other gain/leveling control circuits. Environ-

mental screening is available. Contact the factory

for information.

M/A-COM does not recommend sustained operation near

these survivability limits.

Standard CMOS TTL interface, latch-up will occur if logic

signal is applied prior to power supply.
