Abstract: A method for measuring a sensitivity of a receiver is provided. The method includes: during a first stage, controlling a signal generator to transmit an input test signal to an input node of the receiver, wherein the receiver generates an output test signal on a first output node of the receiver according to the input test signal; calculating a path loss from the input node of the receiver to the first output node of the receiver according to the input test signal and the output test signal; during a second stage, measuring an output noise power on a second output node of the receiver after a load is connected to the input node of the receiver; and calculating the sensitivity of the receiver according to the path loss and the output noise power. The load may be an antenna or a 50-ohm impedance load.

Abstract: A pathloss calibration method used for a radio-frequency communication device can include defining m×n conditions according to m frequency bands and n power gears, obtaining x base pathloss values under x conditions of the m×n conditions on a first route of the radio-frequency communication device, obtaining y anchor pathloss values under y conditions of the m×n conditions on a second route of the radio-frequency communication device, generating y offset values according to the y anchor pathloss values and y base pathloss values of the x base pathloss values where the y base pathloss values are obtained under the y conditions, and generating z anchor pathloss values on the second route according to the y offset values and the x base pathloss values.
