Complies with Directive 2002/95/EC (RoHS)
Product Overview
TRC102 is a highly integrated single chip, zero-IF, multi-channel, low
power RF transceiver. It is an ideal fit for low cost, high volume, two way
short-range wireless applications for use in the unlicensed 400-1000 MHz
frequency bands. The TRC102 is FCC & ETSI certifiable and improves
upon the TRC101 with improved phase noise and is capable of higher
output power. All critical RF and baseband functions are completely
integrated in the chip, thus minimizing external component count and
simplifying and speeding design-ins. Use of a low cost, generic 10MHz
crystal and a low-cost microcontroller is all that is needed to create a
complete link. The TRC102 also incorporates different sleep modes to
reduce overall current consumption and extend battery life. Its small size
with low power consumption makes it ideal for various short range radio
applications.
