The module uses the same antennas to transmit and receive the 802.11b/g RF
signal. An antenna switch is required to isolate the transmit signal from the receive
signal. The antenna switch works by alternately connecting the antennas to either
the transceiver transmit output or the transceiver receive input. To support this
antenna sharing scheme, the module operates in half-duplex mode; receive and
transmit operations do not occur at the same time.
The antenna switch is a digitally controlled 2.4 GHz, 50 ohm, multi-function solid
state switch, controlled by software.
The switch can handle >28dBm of signal on the transmit port. The insertion loss of
the antenna switch is <0.5dB and the receive to transmit port isolation is >23dB.
