868.35 MHz Hybrid Transceiver

The TR8001 hybrid transceiver is ideal for short-range Wireless data applications where robust operation, small size, low power consumption and low cost are required. The TR8001 employs RFMs amplifier-sequenced hybrid (ASH) architecture to achieve this unique blend of character- istics. All critical RF functions are contained in the hybrid, simplifying and speeding design-in. The receiver section of the TR8001 is sensitive and stable. A wide dynamic range log detector, in combination with digital AGC and a compound data slicer, provide robust performance in the presence of on-channel interference or noise. Two stages of SAW filtering provide excellent re- ceiver out-of-band rejection. The transmitter includes provisions for both on-off keyed (OOK) and amplitude-shift keyed (ASK) modulation. The transmitter employs SAW filtering to suppress out- put harmonics, facilitating compliance with ETSI I-ETS 300 220 and similar regulations. By RF Monolithics, Inc.
