Description
M/A-COM’s MAAD-009194-000100 is a GaAs FET
5-bit digital attenuator with a 1 dB minimum step size
and 31 dB total attenuation. The design has been
optimized to minimize phase variation over the at-
tenuation range. This attenuator and integral TTL
driver is in a hermetically sealed ceramic 16-lead
surface mount package.
The MAAD-009194-
000100 is ideally suited for use where accuracy, fast
switching, very low power consumption and low in-
termodulation products are required. Typical appli-
cations include dynamic range setting in precision
receiver circuits and other gain/leveling control cir-
cuits. Environmental screening is available. Contact
