The measurement method includes operations of applying a first gate bias voltage to a gate terminal of a first transistor that is included in a radio frequency (RF) power amplifier during a direct current (DC) measurement period, wherein the first transistor operates in a linear operation mode during the DC measurement period; measuring a first drain-source voltage of the first transistor and a current flowing through the first transistor via a connection node during the DC measurement period; applying a second gate bias voltage and a drain bias voltage to a gate terminal and a drain terminal of a second transistor that is electrically connected to the first transistor via the connection node; and measuring a DC value of the second transistor via the connection node during the DC measurement period.

Measurement method using radio frequency power amplifier

The present invention provides a receiver having an input node, a blocker detector, a translational filter and a low-noise amplifier. The input node is arranged to receive an input signal. The blocker detector is configured to detect if the input signal has a blocker to generate a detection result. The translational filter is configured to filter out an output-of-band blocker of the input signal to generate a filtered input signal at the input node or not filter output the output-of-band blocker of the input signal according to the detection result. The low-noise amplifier is configured to receive the filtered input signal or the input signal to generate an amplified input signal.
