Abstract

The design of a digital subband tuner (SBT) with an embedded GaAs finite-impulse-response (FIR) filter is described. The tuner is used in digital signal processing applications to tune adaptively to narrowband signals for improved signal-to-noise ratio (SNR) and higher signal selectivity against interferers. The SBT performance is maximized using GaAs gate arrays and memory devices designed to support a 400-MHz system clock rate.<>
