A7103B Datasheet | AMICCOM

Features ．A7103A for 315MHz/433MHz, A7103B for 868/ 915MHz. ．High link budget: Distance up to 1Km is possible. For 433MHz, Tx +10d Bm, Rx -108d Bm@ FSK 20Kbps BER<10E-3. -109d Bm @ ASK 20Kbps BER<10E-3. ．Very low current consumption: Typical Tx 14.5m A @ FSK, 7.5m A@ ASK. Rx 8.5m A. ．Very simple control interface: 3~6 control signals. ．Support multi channels. ．High integration: VCO, PLL, PA, LNA, Image Reject Mixer, IF Filter, Limiter, RSSI, Data Slicer, AFC, AGC… ．Very few external ponents: No need external filters. ．Build in image rejection mixer. Selectable IF band width (100, 200, 300 KHz). ．Wide operating range: VDD=2.2~3.3V (IO 2.0~4.2V). T=-40~+85/125℃. ．Auto ramp-up sequence control to optimize power consumption. XtalÆPLLÆ T/RX. ．One receiver for different systems: Switching between ASK/FSK is possible. ．Auto calibration to pensate process/temperature/voltage variation. ．Support typical 4/12/13.56/16MHz low cost crystal.
