摘要:
The present invention relates to a device and a method for regulating the output power of an amplifier stage, e.g. an amplifier stage in a mobile data transmission system.
摘要:
A transmitter includes a transformer that is configured to transform a baseband signal into an amplitude information signal and a phase information signal. The transmitter includes a ramping control unit configured to generate a power control signal. The transmitter includes a mixer that is configured to combine the amplitude information signal with the power control signal and produce a second amplitude information signal. The transmitter includes a modulator that is configured to modulate the second amplitude information signal on the phase information signal and produce an output signal.

摘要:
A transceiver comprising a first frequency signal generator for generating a reception frequency signal, and a second frequency signal generator for generating a transmission frequency signal. The first frequency signal generator is coupled to the second frequency signal generator to supply the reception frequency signal to the second frequency signal generator as a reference frequency signal.
