Title:
TRANSCEIVER AND SIGNAL GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/110814
Kind Code:
A1
Abstract:
A transceiver (1) uses an LO signal, which is a local oscillation signal, to up-convert an IF signal having a given frequency band, thereby generating a transmission signal RFTX. The transceiver (1) also generates an (LO + IF)2 signal and an (LO – IF)2 signal on the basis of the IF signal and the LO signal. A reception signal RFRX is down-converted by use of an LO signal obtained by adding together the (LO + IF)2 signal and the (LO – IF)2 signal, whereby the need for a local oscillation signal generation unit in a reception unit can be eliminated.
