Abstract
An RF receiver includes an RF signal reception path to process an input signal for the receiver for a first mode of the receiver; an oscillator; and a harmonic generator. The harmonic generator generates a harmonic signal in response to operation of the oscillator to replace the input signal with the harmonic signal for a second mode of the receiver.
Claims17
A method comprising:
- using a signal reception path in a radio frequency (RF) receiver to process an input signal for the receiver for a first mode of the receiver;
- using a harmonic generator of the receiver to generate a harmonic signal;
- and
- using the harmonic signal to replace the input signal with the harmonic signal for a second mode of the receiver, wherein the act of using the harmonic generator comprises using a square wave generator or a pulse generator.
