1. Apparatus comprising:
- (i) an input;
(ii) an output;
(iii) a transmit processor configured to process data for transmission by the output;
(iv) a receive processor configured to process data received by the input;
(v) a duplexer connected to the input and output, and including a first port and a second port, the duplexer being configured to pass data received in a first frequency band between one of the input and output and the first port and data received in a second frequency band between one of the input and output and the second port; and
(vi) a transceiver switch including a circulator couplable to the transmit processor and the receive processor, and connected to the transmit processor and receive processor, first port and second port, the transceiver switch being configured to connect either the transmit processor to the second port and switchably connect the receive processor between the first port and the second port, or to connect the receive processor to the first port and switchably connect the transmit processor between the first port and the second port.

Abstract
A base station including at least a transceiver switch is provided enabling the base station to transmit and receive data in either FDD or TDD mode from an antenna. The base station may be provided with a synthesizer which can be retuned from FDD to TDD mode or alternatively, an FDD and a TDD synthesizer and a switch enabling the transmitter and receiver of the base station to process FDD or TDD mode data respectively.
