RFMD shareholders approve all proposals at 2011 AGM


Eight elected directors will serve a one-year term and the RFMD Cash Bonus Plan has also been reapproved.


“With the introduction of the MAAM-009455, we continue to expand our portfolio of high performance amplifiers for CATV infrastructure applications,” said Graham Board, Product Manager. “The MAAM-009455 utilises M/A-COM Tech’s established 0.5 μm MESFET process to deliver a highly linear, 75 Ω, push-pull amplifier with 20.5 dB of small signal gain.”


The MAAM-009455 targets next generation CATV HFC, FTTx, HDTV, and EdgeQAM infrastructure applications, where high gain and low distortion are a requirement. The MAAM-009455 is a highly linear amplifier, with low noise figure and power dissipation. This differential amplifier uses M/A- COM Tech baluns, input and output, in order to ensure best-in-class second order performance. The amplifier also features external feedback, allowing for gain tuning.


The MAAM-009455 exhibits an excellent gain flatness of 0.5 dB typical over the 50 to 1000 MHz operating band. Input return loss has been optimized to achieve better than 20 dB across the band. Very low distortion characteristics provide excellent composite second order (CSO), and composite triple beat (CTB) performance. This amplifier exceeds DOCSIS 3.0 DRFI specifications making it an ideal output stage solution for EdgeQAM head-end infrastructure.


M/A-COM Tech says production quantities and samples of MAAM-009455 are available from stock.


RF Micro Devices, a designer and manufacturer of high-performance radio frequency components and compound semiconductor technologies, has announced that all agenda items at RFMD’s 2011 Annual Meeting of Shareholders were approved by the shareholders.


Eight directors have been elected to serve a one- year term. Approved on an advisory, non-binding basis, the Company’s executive compensation was decided and will be reviewed once a year.


The shareholders also reapproved the RFMD Cash Bonus Plan, pursuant to the provisions of Section 162(m) of the Internal Revenue Code of 1986, as amended.


Finally, the firm has appointed Ernst & Young LLP as its independent registered public accounting firm for the fiscal year ending March 31, 2012.


RFMD is celebrating its 20th anniversary throughout 2011 by continuing to deliver innovative, breakthrough products that reshape its respective product categories. Examples of RFMD’s product and technology leadership include RFMD’s PowerStar power amplifiers and high-power GaN technology.


TriQuint 3G/4G base station filters simplify RF design


The firm says its new family of BTS RF SAWs handle more power, have lower losses and provide very good attenuation.


TriQuint Semiconductor has released five new RF SAW filters that improve performance in 3G/4G network infrastructure designs, offering cost- effective, simplified solutions for LTE, WCDMA and TD-SCDMA applications.
