Abstract:
1. A high frequency wireless integrated circuit transceiver, comprising: digital circuitry operable to produce, receive and process ingoing and outgoing digital signals; transceiver circuitry operable to transmit and receive radio frequency signals based on the outgoing and ingoing digital signals; oscillation control circuitry operable to generate an oscillation control signal; local oscillation generation circuitry operable to generate, based upon the oscillation control signal, a local oscillation to the transceiver circuitry, the local oscillation circuitry including a micro-strip filter sized to have a resonant frequency; wherein the micro-strip filter includes a plurality of selectable tap points and a plurality of selectable capacitive elements, wherein a first combination of selectable micro-strip tap points and at least one selectable capacitive element provides a local oscillation used for a radio frequency that is less than 20 GHz and wherein a second combination of selectable micro-strip tap points and at least one selectable capacitive element provides a local oscillation used for a radio frequency that is greater than or equal to 20 GHz; at least one antenna operably coupled to the front end transceiver circuitry and sized to transmit and receive very high radio frequency signals having a frequency that is at least 20 GHz antenna; and wherein the digital circuitry, transceiver and oscillation control circuitry are formed on the same die.
