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 V_CCand –5.0 V to –8.0 V for V_EEand 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. V_EE= -5 V for the typical numbers given.
