Claim:
1. A radio front-end, comprising: a transmit path comprising a power amplifier; a receive path comprising a low-noise amplifier; and a transmit/receive switch configured to connect the transmit path and the receive path to an antenna, the transmit/receive switch comprising a first switched reactive impedance connected in parallel with the power amplifier on the transmit path and a second switched reactive impedance in parallel with the low-noise amplifier on the receive path, said first switched reactive impedance having an impedance configured to neutralize a reactive impedance of the power amplifier, said second switched reactive impedance having an impedance configured to neutralize a reactive impedance of the low-noise amplifier, the transmit/receive switch being further configured to disconnect the second reactive impedance during reception.
