Abstract

A frequency resolver and a method for using the resolver. The resolver includes an oscillator circuit, a mixer circuit, and a controller circuit. The oscillator circuit is configured to provide at least two oscillated signals. The mixer circuit is coupled to the oscillator circuit and includes a first frequency mixer and a second frequency mixer for mixing an incoming RF transmission with the two oscillated signals. The mixer circuit further is configured to provide a first output signal from the first mixer and a second output signal from the second mixer. The controller circuit is coupled to the mixer circuit and configured to determine whether at least one of the first or second output signals are associated with an upper sideband (USB) frequency or a lower sideband (LSB) frequency of the RF transmission.

First claim

What is claimed is:

1. A radio frequency (RF) resolver, comprising:
an oscillator circuit configured to provide a first oscillated signal and a second oscillated signal that is different from the first oscillated signal;
a mixer circuit coupled to the oscillator circuit, the mixer circuit including first and second frequency mixers for mixing an incoming RF transmission, each of the first and second mixers including a first input, a second input, and an output, the first inputs…
