Abstract
(EN)
The invention discloses a method and device for calculating the insertion loss of a receiving circuit of a radio frequency circuit, and a radio frequency circuit. The method comprises the following steps: receiving the receiving circuit power P1 fed back by a first coupler and received signal power P2 fed back by a second coupler in a predetermined frequency band; separately subtracting P1 with each P2 to obtain an insertion loss value between the first coupler and the second coupler in the predetermined frequency band; and outputting the insertion loss value. According to the method and device disclosed by the invention, the P1 and the P2 necessary for calculating the insertion loss value of the predetermined frequency band in the receiving circuit can be obtained quickly and conveniently through the receiving circuit power P1 and the received signal power P2; the P1 is subtracted with each P2 to obtain the insertion loss value of the predetermined frequency band corresponding to each P2, and the insertion loss value is output, so that a radio frequency engineer can quickly and conveniently test the insertion loss of the receiving circuit of the radio frequency circuit, the difficulty of determining the problem point of the receiving circuit is reduced, and the efficiency of radio frequency debugging is improved.
