Avago introduces new series of WiFi and WiMAX linear amplifier modules

Avago Technologies of San Jose, CA, USA has introduced a new series (MGA-2xx03) of miniature fully matched WiMAX and WiFi power amplifier modules for mobile and fixed wireless data applications.

The MGA-2xx03 series PA modules feature a 3mm x 3mm x 1 mm package and are designed for manufacturers of portable and mobile devices containing WiMAX or high power WiFi links. Consisting of three high gain, fully matched (with no external matching components) PA modules, the series provides high efficiency over a broad frequency bandwidth and meets industry-standard Spectral Emission Mask (SEM) tests operating at 3.3V.

Avago’s MGA-2xx03 linear amplifier modules cover frequency ranges of 2.3 to 2.7GHz (MGA-22003), 3.1 to 3.8GHz (MGA-23003), and 5.1 to 5.9GHz (MGA-25203).

According to the firm, the high gain, low current use, and high linear power over a broad frequency range of its 2xx03 series gives industry designers the option to use a single part to cover the entire band of interest. Previously, multiple narrow band parts were required to achieve performance goals. These fully matched PA modules are designed with a biasing circuit that accounts for manufacturing variation, allowing designers to plan less added system margin.

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

Avago’s MGA-22003 and MGA-23003 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 high gain greater tan 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 a full 23 dBm power at -34 dB EVM with 30 dB gain at 5.4 GHz.

Other features include:

• 50 ohm all RF ports
• Integrated CMOS compatible pins for shutdown and low power mode
• 3 to 5V power supply
• Stable under all loads and conditions
• Operating Temperature: -40 to +85 degrees C

The MGA-2xx03 series of WiFi and WiMAX power amplifiers are sampling now to early customers and will be available for sampling broadly in Q3/2009. Pricing will be under $2.00.
