Patent ID: 7352995

Claim:
A digital microwave transceiver, comprising: means for receiving a signal to be transmitted using a microwave frequency; and means for upconverting the signal onto a predetermined microwave frequency, the upconverting subsystem includes one or more direct digitally tuned circuits for tuning the transceiver wherein each digitally timed circuit comprises a microwave circuit that is being tuned to a predetermined microwave frequency, an electrically tunable element for tuning the microwave circuit to the predetermined microwave frequency, the electrically tunable element being attached to a substrate and further comprising a plurality of tuning signals, means for noise filtering said tuning signals to generate noise filtered tuning signals, a converter, based on the noise filtered tuning signals, that controls the frequency of the microwave circuit to a predetermined microwave frequency and an analog tuning signal that is integrated into the substrate and mounted on said noise filtering means.
