Description
M/A-COM’s AT20-0263 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
ceramic 16-lead surface mount package. The AT20-0263 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. Available with enhanced performance as
fully hermetic version. Environmentally screenable as P/N
AT-263.
Electrical Specifications: T
1. All specifications apply when operated with bias voltages of +5V for Vcc and –5.0V for Vee.
2. This attenuator is guaranteed monotonic.
