TR3001
®
· 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.

Notes:
1. Typical sensitivity data is based on a 10-3 bit error rate (BER), using DC-balanced data. There are two test methods commonly used to
measure OOK/ASK receiver sensitivity, the “100% AM” test method and the “Pulse” test method. Sensitivity data is given for both test meth-
ods. See Appendix 3.8 in the ASH Transceiver Designer’s Guide for the details of each test method, and for sensitivity curves for a 2.2 to
3.7 V supply voltage range at five operating temperatures. The application/test circuit and component values are shown on the next page and
in the Designer’s Guide.
2. At low data rates it is possible to adjust the ASH pulse generator to trade-off some receiver sensitivity for lower operating current. Sensitiv-
ity data and receiver current are given at 2.4 kbps for both high sensitivity operation (RPR = 330 K) and low current operation (RPR = 1100 K).
3. Data is given with the ASH radio matched to a 50 ohm load. Matching component values are given on the next page.
4. See Table 1 on Page 8 for additional information on ASH radio event timing.
