Avago Technologies Launches New High-Gain Linear Amplifier Module for WiMAX

Avago Technologies, a supplier of analog interface components for communications, industrial and consumer applications, announced the launch of a new linear power amplifier module for mobile and fixed wireless data WiMAX (News - Alert) applications.

The new power amplifier module includes Wi-Fi and other cellular radios. The new MGA-22103 module has an aggressive gain shape that limits the noise injected into radio receivers co-located in the same device, enabling WiMAX to coexist with Wi-Fi, GPS, PCS and other radios in handsets, tablets and USB dongles, company officials said.

The MGA-22103 linear power amplifier is cost-effective and meets industry-standard Spectral Emission Mask (SEM) tests operating at 3.3V. The amplifier covers a frequency range of 2.5 to 2.7 GHz. The power amplifier includes integrated RF matching. These features are integrated in a compact 3 mm by 3 mm by 1 mm package, allowing designers to achieve standards-compliant performance in space-constrained designs.

The module can be used for high-linearity applications since it leverages Avago’s GaAs enhancement-mode pHEMT technology, according to company officials. The power amplifier exhibits flat gain and good matching while providing linear power efficiency to meet stringent mask conditions.

The MGA-22103 module meets the IEEE (News - Alert) 802.16 WiMAX mask at over 25 dBm power, with high gain of 35 dB across the band. A low power mode lets operation at 80 mA when only minimal power is required.

The MGA-22103 linear power amplifiers are priced at $2.20 each in 10,000 piece quantities. Modules are available now through the Avago direct sales channel as well as via worldwide distribution partners. The module is available as part of the Sequans SQN1210 reference design for USB dongles.

Earlier this year Avago Technologies, in association with LeCroy, demonstrated 30-Gbps performance using Avago’s new Serializer/Deserializer (SerDes) core in 28-nm process technology and LeCroy’s WaveMaster 8 Zi-A Oscilloscope.
