DENVER, COLORADO - October 27, 2009 - RF Micro Devices, Inc., a global leader in the design and manufacture of high-performance radio frequency systems and solutions, today released the industry's first "green" gallium nitride (GaN) based CATV amplifier modules. The D10040200PL1 and D10040230PL1 are designed for use as power doubler amplifiers in current and next generation CATV infrastructure applications.

The D10040200PL1 and D10040230PL1 are hybrid power doubler amplifier modules designed to provide the final amplifier stage for CATV trunk amplifiers, line extenders, and optical nodes. The parts employ GaAs pHEMT and GaN HEMT die and operate from 45 MHz to 1000 MHz. They provide high output capability, excellent linearity and superior return loss performance with low noise and optimal reliability. With low current and extremely low distortion, the D10040200PL1 and D10040230PL1 are unconditionally stable under all terminations.

The performance of this new family of CATV amplifiers is on par with other industry-leading GaAs CATV Power Doublers, also supplied by RFMD, but with 20% lower current consumption (24V/380mA). With these "green" energy-saving benefits, these products enable designers to fulfill growing requirements for lower energy consumption and assist network operators in their drive to reduce the overall cost of operating CATV networks. The D10040200PL1 and D10040230PL1 are the best performing low-current CATV power doubler amplifiers on the market today.

Bob Van Buskirk, president of RFMD's Multi-Market Products Group (MPG), said, "Network operators worldwide are increasingly focused on reducing the energy costs of operating their wireless and wireline networks. RFMD's high-performance GaN technology satisfies the industry's drive for "green technology" by enabling advanced RF components and products that provide industry-leading power and operate at significantly lower power consumption levels."

RFMD is a leader in III-V semiconductor technology innovation and was the first to introduce GaN CATV amplifier modules, with the launch of the D10040200PH1 and D10040230PH1 high output GaN power doubler CATV amplifier modules in June 2008.

CATV，无线抄表，Femtocell基站等等，应该是III-V半导体的另外增长点，除传统的微波/射频及手机应用。

这周去成都闪电出差，遭遇最无语的飞机航班调整。去的时候航班提前，搞得我们早上四点半就出门；回来的时候又遭遇航班延误，在双流机场呆了足足6个小时，回到北京宿舍的时候已经过了零点。

要办的事情办得还算比较满意，长了不少见识，也更正了不少错误的想法。不过，这几天真累，快散架了。

老板说下周再去合肥一趟。合肥，这个地方陌生又熟悉，四年半了，离开那里。
