DL-RTA7139: Low Power FSK Two-way RF Transceiver Module with AMICCOM A7139 Chip
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.
Features
● Compact size, SMD stamp edge half-hole encapsulation;
● Operating frequency: 433.92 Mhz (other frequencies, 315M ~ 915MHz, can be customized);
● Transmission distance: open air around 1.2 km (indoor test: 10-layer stable transmission);
● Supports FSK, GFSK modulation and programmable control;
● The communication rate ranges from 2 Kbps to 250 Kbps, which is programmable;
● The maximum output power is 20dBm;
● High reception sensitivity: -119dBm@2kbps;
● Low power consumption, receiving current <4mA (AGC Off);
● Low power mode with power consumption <0.3uA, ideal for battery-powered wireless
transmission in long distance
● Independent 64BYTE transmit/receive data buffer
● Switching time between standby and receive state can be set (WOR function), to reduce the
power consumption
● Supports RSSI signal strength detection, and battery low-voltage detection
● Power supply: DC1.9~3.6V
Applications
● ISM band data communication
● Intelligent Building
● Intelligent Home Security
● AMR (Automatic Mobile Robot)
● Wireless remote control
● Architectural Automation
● Wireless Sensor Network
● Energy Control and Management
