    摘要： In a high-frequency amplifier circuit, a power detector detects input power, an A/D converter converts the detection output into a digital signal, and then a digital LPF averages the digital signal to obtain data of the average value of input power level. Control data corresponding to the data of the average value is supplied as a control voltage from a DC-to-DC converter controlling memory to a DC-to-DC converter via a D/A means. Thus, a low output voltage vdd is supplied from the DC-to-DC converter to a power amplifier as circuit supply voltage of the power amplifier at the times of medium and low output power to control unnecessary current consumption by the power amplifier and thereby increase efficiency of the power amplifier at the times of medium and low output power.

    摘要： A RF receiver for modulated RF signals based on a N-port junction (1) providing LO/RF isolation is proposed. N thereby is an integer larger than two, such that the N-port junction (1) can be preferably a three port, four port, five port and six port junction. The N-port junction (1) supplied with a first RF signal at a first input (2) and with a second RF signal originating from a local oscillator (2) at a second input (3). An isolation block (13) comprising an active circuitry (22) is comprised in the N-port junction for isolating the second input (3) from the first input (1). Thereby can be ensured that the LO signals are significantly attenuated at the RF port (2).
