Abstract
A device includes a digital frontend. The digital frontend is configured to digitally modulate symbols for digital signals of a plurality of channels according to a transmission protocol. Each channel is associated with at least one respective carrier frequency within a transmission bandwidth. The digital frontend is further configured to combine the digital signals to obtain a digital output signal. The device further includes an analog frontend having a digital-to-analog converter configured to convert the digital output signal into an analog output signal. The analog frontend also includes a programmable gain amplifier configured to apply an analog gain to the analog output signal. The device further includes a control logic configured to determine the analog gain based on calibration data indicative of the frequency response of the analog frontend across a transmission bandwidth.
