... 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 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 suppress output harmonics, facilitating compliance with ETSI I-ETS 300 220 and similar regulations ...

... Transmitter operation supports two modulation formats, on-off keyed (OOK) modulation, and amplitude-shift keyed (ASK) modulation which is normally used by the TR3100. When OOK modulation is chosen, the transmitter output turns completely off between “1” data pulses. When ASK modulation is chosen, a “1” ...

... O A ±5% resistor value is recommended. In the ASK mode (TR3100), this pin accepts analog modulation (shaped or unshaped data pulses). ASK modulation is practical for data pulses 1 µs or longer. The resistor driving this pin must be low in the receive and power-down (sleep) modes. Please refer to the ASH Transceiver Designer’s Guide for additional information on modulation techniques ...
