Abstract
A communication module includes a variable gain amplifier, a mixer stage responsive to the variable gain amplifier, a post-mixer amplifier stage responsive to the mixer stage, and an off-channel signal detector responsive to the post-mixer amplifier stage. The post-mixer amplifier stage is to produce a first differential signal and a second differential signal. The off-channel signal detector has a first input to receive the first differential signal and has a second input to receive the second differential signal. The off-channel signal detector includes a programmable hysteresis comparator module, and the off-channel signal detector has an output to produce an output signal that indicates whether an off-channel signal condition is detected.
