Abstract
A Radio Frequency (RF) duplexer including Bulk Acoustic Wave Resonators (BAWRs) and an RF filter including BAWRs are provided. The RF duplexer may convert the received signal into a balance signal and output the balance signal via a dual-output port. The RF duplexer may also include a BAWR receiving filter unit including an input end to receive the balance signal from the dual-output port, and an output end used for dual output. The RF duplexer may also include a BAWR transmitting filter unit to transmit a transmitted signal to the antenna via a single-output port.
