Anadigics' WiFi PA enables video transmission system in DJI's Phantom 2 Vision drones

Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA is shipping production volume of its AWL6153 power amplifier (PA) in support of DJI's Phantom 2 Vision and Phantom 2 Vision+ drones. These feature-rich systems include a lightweight, multi-functional integrated aircraft and camera with anti-vibration and stabilization capabilities. The Phantom 2 Vision and Phantom 2 Vision+ drones also include a range extender that increases WiFi distance to 300m and 700m, respectively. In both Phantom 2 Vision models, the drone and range extender each use two AWL6153 power amplifiers for video transmission, i.e. a total of four PA devices per system.

"Our WiFi power amplifiers are renowned for delivering exceptional gain, output power, and linearity, which are critical specifications for stable connectivity at extended range," says Alex Miller, Anadigics' product marketing manager for WiFi Products. The selection of the AWL6153 PA for the DJI Phantom 2 Vision drones exemplifies Anadigics' "ability to deliver value into new market segments," he adds.  

The AWL6153 is part of Anadigics' WiFi infrastructure power amplifier portfolio. Operating in the 2400-2485MHz frequency band, it features what is claimed to be excellent linearity, 30.5dB of linear power gain, and less than 3% EVM (error vector magnitude) at +25dBm output power, providing optimal performance in infrastructure and multimedia applications. The power amplifier also provides what is reckoned to be best-in-class power efficiency and improved thermal characteristics, enabling manufacturers to develop multi-power amplifier solutions that consume less power and are more thermally efficient.

The AWL6153 is fully matched to 50 Ohms at both the RF input and output, so no external matching circuits are required. It is offered in a compact 4mm x 4mm surface-mount package to manage heat dissipation while significantly reducing PCB space requirements.
