摘要:
A transceiver switch circuitry having an antenna port, a receiver port, a first transmitter port and a second transmitter port. The transceiver switch circuitry is configured to be operable in a reception mode to allow reception signals at the antenna port to be forwarded to the receiver port, and in a transmission mode to allow transmission signals, having a center frequency with a wavelength λ, at the first transmitter port and the second transmitter port to be forwarded to the antenna port for transmission. The transceiver switch circuitry has a receive arrangement including a first λ/4 impedance transformer and a first switch circuitry configured to ground the first λ/4 impedance transformer at the receiver port in the transmission mode; and a transmit arrangement having a second λ/4 impedance transformer and a second switch circuitry configured to ground a second side of the second λ/4 impedance transformer in the reception mode.
