High-performance FSK Transceiver Module with AMICCOM A7139 chip
Module introduction
DL-RTA7139 was designed base on AMICCOM A7139 wireless transceiver chip from Taiwan. It is a compact and low power wireless transceiver module. AMICCOM A7139 is an ISM band wireless transceiver chip, mainly set to 315/433/470/868/915/MHz ISM/SRD frequency bands, with very low power consumption (e.g.: under 434MHz band, power consumption in RX mode is just 3.8mA).
It is ideal for battery-powered long-distance wireless transmission, and provides a very good link budget, with high class E power output up to 20dBm, and a maximum transmission rate of 250Kbps. Users can easily develop wireless products with stable performance and high reliability by this module, without having a deep understanding of RF circuit design.
