1. A switch arrangement for a radio frequency circuit, the switch arrangement comprising:
a first switch comprising a single pole, the first switch being configurable to selectively connect said pole to one of at least a first communication path and a second communication path; and a second switch comprising a single pole, the second switch being configurable to selectively connect said pole to one of at least the first communication path and the second communication path, wherein the first switch is configurable for a first mode of operation to connect a radio frequency signal received at the pole of the first switch via a power amplifier from a processing system to the first communication path to form at least a part of a transmitter chain for transmitting radio frequency signals in the first mode; wherein the second switch is configurable for the first mode of operation to connect the pole of the second switch to the first communication path for receiving a radio frequency signal at the pole of the second switch via the first communication path to form at least a part of a receiver chain for receiving radio frequency signals in the first mode; and wherein the first switch is configurable for a second mode of operation to connect a radio frequency signal received at the pole of the first switch via a said power amplifier from a said processing system to the second communication path to form at least a part of a second transmitter chain for transmitting radio frequency signals in the second mode. |
