A TRANSCEIVER SWITCH CIRCUITRY
A transceiver switch circuitry (30) comprising an antenna port (18), a receiver port (17), a first transmitter port (15) and a second transmitter port (16). The transceiver switch circuitry is configured to be operable in a reception mode to allow reception signals (31) at the antenna port (18) to be forwarded to the receiver port (17), and in a transmission mode to allow transmission signals (36), having a center frequency with a wavelength λ, at the first transmitter port (15) and the second transmitter port (16) to be forwarded to the antenna port (18) for transmission. The transceiver switch circuitry (30) further comprises a receive arrangement comprising a first λ/4 impedance transformer (32) and a first switch circuitry (33) configured to ground the first λ/4 impedance transformer (32) at the receiver port (17) in the transmission mode; and a transmit arrangement comprising a second λ/4 impedance transformer (26) and a second switch circuitry (35) configured to ground a second side of the second λ/4 impedance transformer (26) in the reception mode.
