Abstract
A wireless communications device includes an antenna that receives a first signal at a first radio frequency and a second signal at a second radio frequency and converts the first and second signals into a composite radio frequency (RF) signal. A first oscillator outputs a first oscillator signal at a first frequency and a second oscillator outputs a second oscillator signal at a second frequency. A demodulator receives the composite RF signal and the first and second oscillator signals. The oscillator signals are selected so that the demodulator generates a low frequency signal with components of the first and second signals occupying a common frequency band. The wireless communications device allows executing a “Soft Handoff” even when the first and second radio frequencies are different.
