Abstract
Provided are a frequency mixer, including: a transconductance circuit connected to an input signal terminal, and configured to generate a differential signal according to an input signal from the input signal terminal and output the differential signal through first and second output terminals of the transconductance circuit; a switch circuit connected to a local oscillator signal terminal and the first and second output terminals of the transconductance circuit, and configured to perform frequency mixing on a local oscillator signal from the local oscillator signal terminal and the differential signal to generate a mixed signal and output the mixed signal through first and second output terminals of the switch circuit; a load circuit connected to an output signal terminal and configured to provide a load; and an amplification circuit connected between the switch circuit and the load circuit and configured to amplify the mixed signal. A transceiver is also provided.
