Linear PAs for Wi-Fi and WiMAX

8 July 2009 Telecoms, Datacoms, Wireless, IoT

Avago Technologies has announced a new series of miniature, fully matched WiMAX and Wi-Fi power amplifier (PA) modules for mobile and fixed wireless data applications.

The MGA-2xx03 series consists of three high-gain, fully matched (with no external matching components) PA modules that provide high efficiency over a broad frequency bandwidth and meet industry-standard spectral emission mask (SEM) tests operating at 3,3 V. The modules measure just 3 x 3 x 1 mm and cover frequency ranges of 2,3 to 2,7 GHz (MGA-22003), 3,1 to 3,8 GHz (MGA-23003) and 5,1 to 5,9 GHz (MGA-25203).

The high gain, low current use, and high linear power over a broad frequency range gives industry the option to use a single part to cover the entire band of interest. These fully matched PA modules are designed with a biasing circuit that accounts for manufacturing variation, allowing designers to plan less added system margin, which can reduce costs.

Designed using Avago's proprietary GaAs enhancement-mode pHEMT technology, the MGA-2xx03 series can be used for most high-linearity applications. The modules exhibit flat gain and good matching while providing linear power efficiency to meet stringent mask conditions.

The MGA-22003 and MGA-23003 are part of a complete RF front end solution for WiMAX applications. These two parts can be paired with a new Avago single-pole four-throw (SP4T) switch detector module to include all the front end RF functionality. The MGA-22003 meets the WiMAX forum 802.16 mask at over 25 dBm power, and the MGA-23003 meets the ETSI 802.16 mask at over 25 dBm power. Both have gain greater than 34 dB across the bands. Additionally, a low power mode allows operation at approximately 100 mA when only low power is required. The MGA-25203 generates 23 dBm power at -34 dB EVM with 30 dB gain at 5,4 GHz.
