RADIO-FREQUENCY RECEIVER, RADIO-FREQUENCY RECEIVING SYSTEM, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2024/046172

A9

Provided in the present application are a radio-frequency receiver, a radio-frequency receiving system, and an electronic device, which are used for solving the problem of how to optimize an insertion loss when different numbers of CA combinations are realized. The radio-frequency receiving system of an electronic device comprises a first radio-frequency receiver, wherein the first radio-frequency receiver comprises at least one first port, a first selection switch, a plurality of first filters, a plurality of second selection switches, a plurality of first amplifiers, two second ports and a switch assembly. The first selection switch and the second selection switches may choose to conduct at least one signal transmission link in the first radio-frequency receiver. The switch assembly may enable the first radio-frequency receiver to receive frequency-band signals, the number of which is less than or equal to the number of first amplifiers, and when the frequency-band signals include frequency-band signals gated by second filters which are discretely arranged outside the first radio-frequency receiver, and all these frequency-band signals may be transmitted from the first radio-frequency receiver to a processing circuit of the electronic device, a signal transmission path is relatively short, and an insertion loss is optimized.
