DR8100 Datasheet, PDF (1/7 Pages) Murata Manufacturing Co., Ltd. – 916.50 MHz Transceiver Module

• 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 under FCC 15.247 Regulations
• Digital Spread Spectrum Output
The DR8100 hybrid transceiver module is ideal for short-range wireless data applications where robust
operation, small size, low power consumption and low cost are required. The DR8100 utilizes RFM’s TR8100
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 DR8100
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 uses an internal “digital
modulation” BPSK spreading code, with data carried by either OOK or ASK modulation. The transmitter
employs SAW filtering to suppress output harmonics, facilitating compliance with FCC 15.247 regulations.
