Mimix Introduces 5 V Medium Power Amplifier

October 24, 2008

Mimix Broadband Inc. introduces a 5 V InGaP HBT amplifier that combines medium power and high gain with low power consumption. This versatile, multi-purpose amplifier, identified as CGB8001-SC, consumes 100 mA of current and covers DC to 2.8 GHz frequency bands with 27 dBm P1dB and 15.5 dB gain at 2.1 GHz.

Designed for 5 V applications, this medium power amplifier is suitable for high linearity transmit, receive and IF applications, including CATV, 3G, WiBro and WiMAX. The low current consumption and high linear performance under complex modulation makes the CGB8001-SC an ideal output stage for multi-carrier applications. The amplifier is offered in an industry standard, RoHS compliant, SOT-89 package and includes an integrated active bias circuit and ESD protection, significantly enhancing quality, reliability and ruggedness.

“The integrated ESD protection, low thermal resistance and low power consumption increase the MTTF of the CGB8001-SC, making it a robust gain block solution,” said Amer Droubi, product manager, Mimix Broadband Inc. “Furthermore, the integrated active bias circuit minimizes performance variation over temperature and enables direct operation from +5 V supply, eliminating the need for an external dropping resistor.”
