Abstract: The present application discloses a radio frequency (RF) device. The radio frequency device includes a power amplifier, a power detector, and a digital signal processor (DSP). The power amplifier outputs a RF signal. The power detector receives the RF signal, and performs a plurality of calibration operations to generate a plurality of calibration voltages corresponding to a plurality of bias voltage, wherein the calibration operations are performed at the bias voltages respectively, and the calibration voltages are temperature-correlated due to that electrical characteristics of the power detector are temperature-correlated. The DSP controls the power detector to operate at the bias voltages, obtains an index voltage for indicating power of the RF signal by performing calculations upon the calibration voltages to reduce temperature dependency of the index voltage, and adjusts a gain of the power amplifier according to the index voltage.

Abstract: The present application discloses a radar system. The radar system includes a first subarray, a second subarray, and a third subarray. Antennas in the first subarray and the second subarray are disposed along a first axis, and antennas in the third subarray are disposed along a second axis. When scanning a radar coverage of the radar system, the radar system utilizes the first subarray and the second subarray as RF signal transceivers and utilizes the third subarray as a RF signal receiver to scan a first detection distance range according to first signal parameters and scan a second detection distance range according to second signal parameters. A maximum distance measured from the radar system to each detectable location in the first detection distance range is less than or equal to a minimum distance measured from the radar system to each detectable location in the second detection distance range.
