5.4 Single Antenna Option
The AMIS-53050 is designed such that when the transmitter or the receiver is off, the respective pin is grounded. This provides a
known impedance for the off port (transmit or receive), in order to allow the use of a single circuit topology combining the receiver and
the transmitter into a single antenna. In the AMIS-53050, a single register is used to set the transmit and receive frequency, resulting in
the same transmit and receive frequency. Therefore, the simple method to combine the transmitter and the receiver into a single
antenna will lead to either a reduction in transmit output power or less sensitivity in the receiver.
