Abstract
A discrete time bandpass filter element (103) having multiple stages (201, 202, 203, 204, 205) for use in a time division duplex radio protocol communications system including an automatic gain control. Discrete time bandpass filter is used to generate delay and can replace SAW filters in a wireless frequency translating repeater.
