Patent ID: 7555272

Claim:
A transmission arrangement comprising: a baseband signal processing unit comprising an in-phase signal path and a quadrature signal path, a first programmable amplifier comprising a first control input configured to accept a first discrete valued digital gain control signal, the first programmable amplifier comprising an amplifier component arranged in the in-phase signal path and an amplifier component arranged in the quadrature signal path, and a passive, programmable attenuator comprising a control input configured to accept a second discrete valued digital gain control signal, passive, programmable attenuator comprising an attenuator component arranged in the in-phase signal path and an attenuator component arranged in the quadrature signal path; a quadrature modulator comprising a first input coupled to the in-phase signal path, a second input coupled to the quadrature signal path, and an output; a radio frequency path coupled to the output of the quadrature modulator, the radio frequency path comprising a second programmable amplifier configured to accept a third discrete valued digital gain control signal; and a control unit providing the first, second and third digital gain control signals.
