RF Micro Devices, Inc., a leader in the design and manufacture of high-performance radio systems and solutions for applications that drive mobile communications, last week announced the introduction and sampling of Gallium Nitride (GaN) wideband power amplifier ICs to Tier 1 WiMAX, cellular base station and Public Mobile Radio (PMR) customers. The family achieves superior performance in gain, output power and efficiency across a broad range of frequencies as compared to currently available gallium arsenide (GaAs) and silicon LDMOS products.

"Our GaN process technology positions RFMD to provide customers with the high-power, broadband solutions needed to meet growing customer demand for more cost-effective and more efficient deployment of next-generation wireless infrastructure," said Jeff Shealy, RFMD Vice President, Infrastructure Product Group. "RFMD's GaN power ICs deliver a simple, single amplifier solution for wideband applications dependant on maximizing power, bandwidth and efficiency."

The new family includes multiple parts, RF3821 (8W P1dB WiMAX PA, 2.3-2.7GHz), RF 3823 (8W P1dB WiMAX PA, 3.3-3.8GHz), RF3822 (14W saturated power Public Mobile Radio PA, 100-1000MHz), and RF 3820 (8W P1dB cellular PA, 1.8-2.2GHz). Both WiMAX power amplifier ICs provide 29dBm linear output power with 2.5% EVM and flat gain of 11dB across multiple bands. The cellular power amplifier IC provides 27dBm linear output power with -50dBc ACPR and flat gain of 13dB across DCS/PCS/W-CDMA frequency bands. The PMR power amplifier IC provides 14W to 12W saturated output power and flat gain of 11.5dB with PAE of 65% mid band at 500MHz. The designs operate on a 28V rail and include internal-matching elements to deliver a 50-ohm interface over the band of operation and are packaged in a thermally enhanced AlN package for efficient heat removal.

RFMD anticipates production shipments of the GaN power amplifiers will commence in calendar year 2007.
