Recently, DreamLNK released its brand-new Wireless Module DL-A7149-S. It is an FSK Transceiver Module based on the AMICCOM A7149 RF chip, which delivers an ultralow power consumption of 1.8mA (receiving current, AGC Off, and -120dBm high receiving sensitivity). It will be ideal for battery-powered long-distance wireless transmission applications.


The DL-A7149-s module's RF core AMICCOM A7149 follows the low receive current of former AMiCcoM A7139, The operation mode of A7149 is the same as A7139.both of which are operated by external MCU through SPI interface to operate RF mode and access the but in FIFO. However, the receiving current of A7139 is much lower, inheriting the excellent RF performance of A7139, the working current of A7149 is only half of A7139.

The modulation mode can be selected as fSK or GFK. And it has two versions: 43MHz/470MHz, and 868MHz/915MHz.And here below are its main advantages.


1. Bult in RSSI (Received signal strength indication) can help detect clean transmission channels, which can make it work stably in various environments

2. With the AFC (Automatic frequency Compensation) function, which can solve the sensitivity degradation caused by RF frequency offset.

3. Ultra Long Range: it can achieve 1KM communication range in an open space (without interference).

4. High Receiving Sensitivity:-120dBm@2Kbps, IFBW:50khz.

5. Compact Size: ultra-small packaging surface mount design: 12.5*12mm (only half the size of a coin).

6. Ultra-low power consumption with only 1.8mA at full receiving state, best for battery powered applications.

7. Wake on Radio (WOR): switching time between standby and receiving state can be set to reduce power consumption.
