Mimix Broadband, Inc. Introduces Family of Pre-Matched HBT Power Amplifiers Specifically Designed for WiMAX Applications

Plastic, surface mount packaged amplifiers provide unparalleled performance, flexibility and cost savings

June 27, 2006, Houston, Texas - Mimix Broadband introduces today a family of internally pre-matched power amplifiers designed for linear WiMAX applications at 700 MHz, 2.5 GHz and 3.5 GHz. These devices are processed in a highly repeatable InGaP high voltage HBT process and include on-chip diodes for ESD protection. This family of devices achieves 11 dB of gain and less than 2.5% EVM at 30 dBm output power, with an OFDM input signal and a peak to average ratio (PAR) of 9 dB. The devices operate off a single supply voltage up to 12V and include internal active bias circuitry. The CHV family includes the added feature of analog adjustment of bias current to address a variety of applications.

These linear power amplifiers, identified as CHV2707, CHV2710 and CHV2711, operate at 700 MHz, 2.5 GHz and 3.5 GHz respectively. Evaluation boards are available to help engineers test the products and apply them to their designs.

"The complex data formats associated with WiMAX signals make it essential that these amplifiers provide exceptional linearity at the highest data transmission format, and that they are adjustable when lower data formats are used. By delivering 1W average power under maximum data transmission, including on-chip bias circuitry, and providing a separate bias current adjustment in a standard QFN plastic package, we provide our broadband customers with unparalleled performance, flexibility and cost savings," stated Damian McCann, CTO of Mimix Broadband, Inc.

Engineering samples are available today from stock in small quantities. Technical support is also available from Mimix's applications engineers at 281.988.4600. The datasheets and additional product information can be obtained from the Mimix Broadband website at www.mimixbroadband.com .
