Toshiba TC32306FTG Single-Chip RF Transceiver
Toshiba TC32306FTG Single-Chip RF Transceiver for Low-Power Systems offers many of the functions required in UHF-band transceiver applications. The TC32306FTG is built on Toshiba's 0.13µm RFCMOS process and supports ASK/FSK modulation with a current consumption of TX 12mA at +10dBm output level / RX 9.7mA / battery saving 0μA (typical). This device integrates LNA, a mixer, IF filter, IF AMP, RSSI, a signal detector, bit rate filter, data comparator, PLL, VCO, and PA into a single IC. The transceiver's digital processing can significantly reduce the number of external components and allow fine adjustments. Toshiba TC32306FTG Single-Chip RF Transceiver is ideal for a variety of remote keyless entry (RKE) and automotive equipment applications, including answerback functions that detect and transmit vehicle status information.
