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.
