TR7002 Datasheet, PDF (1/15 Pages) Murata Manufacturing Co., Ltd. – 418.00 MHz Hybrid Transceiver

• Designed for Short-Range Wireless Data Communications
• Supports RF Data Transmission Rates Up to 115.2 kbps
• 3 V, Low Current Operation plus Sleep Mode
• Up to 10 mW Transmitter Power
• Complies with Directive 2002/95/EC
The TR7002 hybrid transceiver is ideal for short-range wireless data applications where robust operation,
small size, low power consumption and low cost are required. The TR7002 employs RFM’s amplifier-
sequenced hybrid (ASH) architecture to achieve this unique blend of characteristics. All critical RF functions
are contained in the hybrid, simplifying and speeding design-in. The receiver section of the TR7002 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 receiver 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 output harmonics, facilitating compliance with FCC/ETSI I-ETS 300 220 and similar regulations.
