Avago Technologies Enables WiMAX to Coexist with Other Radios in Portable Devices with New High-Gain Linear Amplifier Module
Avago Technologies announced a new linear power amplifier module for mobile and fixed wireless data WiMAX applications that include WiFi and other cellular radios. The new MGA-22103 module features an aggressive gain shape that limits the noise injected into radio receivers co-located in the same device, enabling WiMAX to coexist with WiFi, GPS, PCS and other radios in handsets, tablets, USB dongles and other portable electronics.
The MGA-22103 linear power amplifier is cost-effective and meets
industry-standard Spectral Emission Mask (SEM) tests operating at 3.3V. Covering
a frequency range of 2.5 to 2.7 GHz, the power amplifier includes fully
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.
Leveraging Avago proprietary GaAs enhancement-mode pHEMT technology, the
MGA-22103 module can be used for most high-linearity applications. With superior
performance across a range of voltage and temperature levels, the module
exhibits flat gain and good matching while providing linear power efficiency to
meet stringent mask conditions. The MGA-22103 module meets the IEEE 802.16 WiMAX
mask at over 25 dBm power, with high gain of 35 dB across the band.
Additionally, a low power mode allows operation at approximately 80 mA when only
minimal power is required.
Additional MGA-22103 Product Features
- Integrated CMOS compatible pins for shutdown and low power mode
- +25 dBm Linear Output Power
- 2.5% error vector magnitude (EVM) 16 QAM WiMAX Modulation at +25 dBm
- Stable under all loads and conditions
- Operating Temperature: -40 to +85°C
U.S. Pricing and Availability
- The MGA-22103 linear power amplifiers are priced at $2.20 each in 10,000
piece quantities. Samples and production quantities are available now
through the Avago direct sales channel and via worldwide distribution
partners. The module is available as part of the Sequans SQN1210 reference
design for USB dongles.
