DR7001-EV Datasheet, PDF (1/8 Pages) Murata Manufacturing Co., Ltd. – 315.00 MHz Transceiver Evaluation 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
The DR7001-EV 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 DR7001-EV utilizes RFM’s
TR7001 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 DR7001-EV 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 and similar regulations.
