1. Descriptions: The Airwave AWM683TX - AWM687TX are compact A/V RF modules that use the popular 5.8GHz ISM band. They are designed with high reliability. Airwave RF modules can transmit/receive a wide band audio & video signals for several hundred feet in open areas. AWM687TX: 14dBm AWM683TX: 20dBm
2. Feature: Use worldwide 5.8GHz ISM band Design in compact size and low power consumption Reach highly efficient FM-FM modulation/demodulation scheme Be compatible with both NTSC and PAL video formats Integrate Audio/Video input and output onto one module base-band PCB Don’t need external Audio circuit Provide with 7 selectable channels Set tack switch for channel selection
3. Application: AV Sender Baby monitor Surveillance Wireless Camera
