1. General Description

The TC32306FTG is a single-chip RF transceiver, which

provides many of the functions required for UHF-band

transceiver applications. It has the most features transmitting

and receiving the signal.

Furthermore, by digital processing, it can reduce significantly the

number of external components and allow fine adjustments.

Various type of applications are supported by this chip as

configuring various settings such as supply voltage, frequency,

modulation and detection

2. Applications

Remote keyless entry (remote door lock / unlock of equipment),

automotive equipment applications such as tire pressure monitoring system, and remote controller, etc
