Radio Control Circuit
The radio is controlled by a custom-made integrated circuit. This circuit
includes a digital discriminator for the receiver. Control of the radio and
trimming of the modulation index of the transmitter is performed by D/A
converters in the circuit. Alarm and other signals from the radio part (RSSI,
Temperature, Transmitter power and Reflected power) are measured with A/D
converters in this circuit.
6.2.6
Filter
A high performance low loss duplex filter is used to achieve sufficient isolation
between the receiver and the transmitter.
