- Above circuit is a 5V use. For 3V use, connect SW2 to low level, and
be short circuit in SW1.
- Above circuit is a use for 315MHz and the circuit parts constants are
suitable for that frequency. For other frequency use, see Table 13-1.
- Above circuit is SPI Mode and external PC controls to read or write
register of TC32306FTG,
- In above circuit, a control of an antenna switch is not use.
- The capacitor C5 and C6 is adjusted by a trimmer capacitor.
