GAIN COMPENSATION IN AN ULTRA-WIDEBAND TRANSCEIVER |
摘要 |
A circuit for providing gain compensation to a swept frequency response in an ultra-wideband system includes using a variable amplitude IF signal into a gigahertz mixer to control the amplitude of a ultra-wideband transmitter. The variable amplitude IF signal is generated by a multiplier receiving a fixed-level intermediate frequency (IF) signal and a gain control input. The gain control input being provided by an digital-to-analog converter controlled by gain control values in a look-up table. The values of the look-up table are generated by inverting, normalizing, and scaling the uncompensated gain response of the ultra-wideband system. The gain compensated system produces a substantially flat amplitude response at the output of a quadrature receiver.
