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 inte-
gral 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
performance as fully hermetic version. Environmen-
tally screenable as P/N AT-107-PIN.

2. All specifications apply when operated with bias voltages of +5V for VCC and –5.0 V to –8.0 V for VEE and 50Ω 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 10KΩ resistor, or an RF choke.
5.
VEE = -5 V for the typical numbers given.
