Table 21: RF Input Electrical Characteristics
9.2 Transmitter
The RF transmitter is a non-linear open drain device. It requires a DC signal path to RFPWR, which is the output of the internal power
supply to the transmitter. The transmitter is switched On and Off with the serial transmit data stream. To achieve the desired output
waveform, a tuned external resonant circuit is required. This resonant circuit should be designed to achieve the desired output
frequency. This circuit includes a parallel LC tank (Lp and Cp) tuned to 402MHz (including internal capacitance), as well as a series LC
(Ls and Cs) to produce a 403MHz output. The transmitter output is also to be filtered in order to reduce the harmonics to acceptable
levels. It is further required that the transmitter output power level is programmed, that the transmit frequency is tuned and that the data
rate is selected, respectively (Table 22).
Table 23 lists some characteristic parameters for the transmitter, while a typical transmitter output waveform is shown in Fig. 8.
