Overview RI-RFM-006A is a CMOS-technology based RF-module IC which integrates all transmitter-receiver functions required for constructing a TIRIS Read-Write System into one single chip. RI-RFM-006A consists of a transmitter signal control logic which generates signals for transmission and for sending the data you wrote to a remote TIRIS transponder, and a receiver amplifies and demodulates frequency shift keyed (FSK) signals received from this transponder. Therefore, RI-RFM-006A is beneficially usable for constructing, in particular, a compact TIRIS Read- Write System at a reduced cost. Furthermore, demodulation of the FSK signals received in its receiver from a remote transponder is entirely digitized; this completely eliminates the need of regulations and lessens the number of required external parts, thus enhancing the operational reliability of the system.
