Description
M/A-COM’s AT-263 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 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.
screening is available. Contact the factory for information.
Electrical Specifications
(From –55°C to +85°C)
1. All specifications apply when operated with bias voltages of +5V for Vcc and –5.0V for Vee.
2. This attenuator is guaranteed monotonic.
