TR3001 Datasheet, PDF (1/12 Pages) RF Monolithics, Inc – 315.00 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
· Stable, Easy to Use, Low External Parts Count
The TR3001 hybrid transceiver is ideal for short-range wireless data applications where robust
operation, small size, low power consumption and low cost are required. The TR3001 employs
RFM’s 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 TR3001 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
output harmonics, facilitating compliance with FCC Part 15 and similar regulations.
