TR3100
®
· Designed for Short-Range Wireless Data Communications
· Supports RF Data Transmission Rates Up to 576 kbps
· 3 V, Low Current Operation plus Sleep Mode
· Stable, Easy to Use, Low External Parts Count
The TR3100 hybrid transceiver is ideal for short-range wireless data applications where robust
operation, small size, low power consumption and low cost are required. The TR3100 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 TR3100 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 TR3100 is optimized for RF data rates from 230.4 to 576 kbps
using amplitude-shift keyed (ASK) modulation. The transmitter employs SAW filtering to sup-
press output harmonics, facilitating compliance with ETSI I-ETS 300 220 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. The application/test circuit and compo-
nent values are shown on the next page.
2. Data is given with the ASH radio matched to a 50 ohm load. Matching component values are given on the next page.
3. See Table 1 on Page 8 for additional information on ASH radio event timing.
