2.0 Functional Description
The TRC105 is a single-chip transceiver that can operate in the 300-510 MHz frequency range. The TRC105
supports two modulation schemes - FSK and OOK. The TRC105 ’ s highly integrated architecture requires a mini-
mum of external components, while maintaining design flexibility. All major RF communication parameters are
programmable and most can be dynamically set. The TRC105 is optimized for very low power consumption (2.7
mA typical in receiver mode). It complies with European ETSI, FCC Part 15 and Canadian RSS-210 regulatory
standards. Advanced digital features including the TX/RX FIFO and the packet handling data mode significantly
reduce the load on the host microcontroller.
Figure 1
The receiver is based on a superheterodyne architecture. It is composed of the following major blocks:
?
?
?
An LNA that provides low noise RF gain followed by an RF band-pass filter.
A first mixer which down-converts the RF signal to an intermediate frequency equal to 1/9th of the carrier
frequency.
A variable gain first IF preamplifier followed by two second mixers which down convert the first IF signal to
I and Q signals at a low frequency (zero-IF for FSK, low-IF for OOK).
