Patent ID: 6990143

Claim:
A radio device comprising: a receiver module, wherein the receiver module comprises: low-noise amplifier module operably coupled to convert an inbound radio frequency (RF) signal into an amplified inbound RF signal; down converter module operably coupled to convert the amplified inbound RF signal into an inbound baseband (BB) signal based on a local oscillator (LO) module input; demodulator module operably coupled to produce inbound data by processing the inbound BB signal in accordance with one of a plurality of radio transceiving standards; a transmitter module, wherein the transmitter module comprises: modulator module operably coupled to produce an outbound BB signal by processing outbound data in accordance with the one of the plurality of radio transceiving standards; up converter module operably coupled to convert outbound BB signal into an outbound RF signal based on the local oscillator (LO) module input; power amplifier module operably coupled to convert the outbound RF signal into an amplified outbound RF signal; and the LO module, wherein the LO module comprises: an LO generator module operably coupled to generate a LO clock; a fifty percent duty cycle clock module operably coupled to generate a fifty percent duty cycle clock based on the LO clock; wherein the fifty percent duty cycle clock module comprises: edge generator operably coupled to generate a clean edge of the LO clock; controllable delay module operably coupled to produce a delayed edge from the clean edge based on a duty cycle control signal; duty cycle control loop module operably coupled to generate the duty cycle control signal based on the delayed edge and the LO clock; and reset circuit operably coupled to reset the edge generator to produce a second edge, wherein the second edge is delayed by the controllable delay module to produce a second delayed edge such that the delayed edge and the second delayed edge constitute one period of the fifty percent duty cycle clock.
