Description
M/A-COM's AT20-0107 is a GaAs FET 6-bit digital
attenuator with a 0.5 dB minimum step size and a 31.5 dB
total attenuation. This attenuator and integral TTL driver is
in a ceramic 24-lead surface mount package. The AT20-
0107 is ideally suited for use where accuracy, fast speed,
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. Available with enhanced perform-
ance as fully hermetic version. Environmentally screenable
as P/N AT-107.

1. Above reference insertion loss.
2. All specifications apply when operated with bias voltages of +5V for VCC and –5.0 V to –8.0 V for VEE and 50O impedance at all
ports unless otherwise stated.
3. This attenuator is guaranteed monotonic.
4. For the attenuator to meet the guaranteed specifications, it is necessary to have a DC return on either RF1 or RF2. The DC
return can be either a 10KO resistor, or an RF choke.
5. VEE = -5 V for the typical numbers given.
