Design Kit – 5.8GHz Wideband FM Receiver Module

1. Descriptions:

The Airwave AWM682RX 5.8GHz Audio/Video wireless RF receiver module uses the popular 5.8GHz ISM band. Designed with high reliability, the Airwave RF receiver module is compliant with the criteria of FCC and R&TTE.

The AWM682 RX module uses down conversion concept to convert the 5.8GHz FM RF signal to 480 MHz IF signal, and then obtain base band via PLL FM demodulation IC.

2. Feature:

Worldwide 5.8GHz ISM band (5725 MHzД5875 MHz).

Conform to R&TTE & FCC stipulation.

Compatible with both NTSC and PAL video formats.

Compact size and low power consumption.

Highly efficient FM-FM modulation/demodulation scheme.

Integrating Audio/Video input and output into one module base band PCB.

Provide with 7 selectable channels.

Received signal strength indicator (RSSI).

3. Application:

AV Sender

Baby Monitor

Surveillance

Wireless Camera
