Abstract:
1. An apparatus for generating local oscillator signals, comprising: a local oscillator generator module having a plurality of local oscillator outputs and a plurality of injection signal inputs, the local oscillator generator module being configured to generate local oscillator signals on the local oscillator outputs based on injection signals received on the injection signal inputs; and an injection signal generator module coupled to the local oscillator generator module, the injection signal generator module having a plurality of local oscillator inputs and a plurality of injection signal outputs, the local oscillator inputs being coupled to the local oscillator outputs, the injection signal outputs being coupled to the injection signal inputs, the injection signal generator module being configured to generate injection signals on the injection signal outputs based on the local oscillator signals received on the local oscillator inputs and based on a received voltage controlled oscillator (VCO) signal, wherein the injection signal generator module is programmable to concurrently provide at least three different sets of injection signals.
