Since January 2011, RFMD has repurchased $49.9 million of its common stock under this program, leaving it with additional authorisation of up to $150.1 million under the program as a result of this extension.
RFMD’s share repurchase program authorises the company to repurchase shares from time to time through solicited or unsolicited transactions in the open market or in privately negotiated transactions.
The number of shares to be purchased and the timing of the purchases will be based on market conditions RFMD extends share repurchase program and other factors.
The firm says the program may be discontinued at any time.
Rubicon has shipped 400,000 large dimension sapphire wafers
The wafers are building block for LEDs used in HDTVs, laptops, smart phones and tablets and RFICs
Rubicon Technology has shipped a total of 400,000 large diameter sapphire wafers to LED and SoS/ RFIC manufacturers.
Sapphire is a key building block for LEDs used in HDTVs, laptops, smart phones and tablets. Another significant market for sapphire is Silicon- on-Sapphire (SoS) Radio Frequency Integrated Circuits (RFICs).
SoS RFIC chips deliver high RF performance with low power consumption, a small form factor, and significantly reduced crosstalk in antenna applications that are pervasive in smart phones and other consumer devices.
Rubicon claims it was the first firm to develop large diameter sapphire wafers for use in the RFIC market and customise needs for the LED industry.
“This latest milestone demonstrates Rubicon’s continuing leadership in the volume delivery of high quality large-diameter sapphire wafers,” says

Raja M. Parvez, President and CEO of Rubicon Technology.
“Our emphasis on vertical integration - achieving cost efficiencies and control of sapphire production – enables us to scale production and ensures our customers an unparalleled, reliable supply of high quality, large diameter sapphire wafers that meet their unique and exacting specifications. Rubicon’s capabilities are increasingly important as LED manufacturers seek to reduce costs throughout the manufacturing process to make LED-based lighting more affordable for consumers and encourage adoption worldwide.”
IMS Research estimates that the overall LED market will reach nearly $10.9 billion in 2012 with $2.9 billion in lighting. By 2015, IMS projects that the LED market will reach $13.9 billion with the lighting market nearly doubling to $5.8 billion in three year.
RFMD Introduces 5GHz WiFi Module for 802.11ac Notebook and Mobile Equipment Applications
RF Micro Devices the designer and manufacturer of high-performance radio frequency components, today introduced the highly-integrated RFFM4501E front end module (FEM) for 802.11ac notebook and mobile equipment applications. RFMD’s newest WiFi FEM meets or exceeds the system requirements for 802.11ac connectivity in the 5.150GHz – 5.850GHz frequency band and is optimized to support multiple applications, including notebooks, mobile routers, and low-power customer premises systems.
The RFFM4501E integrates a +17.5dBm (80MHz MCS9) PA at 3.3V, a low insertion loss/high isolation single pole two throw (SP2T) switch, harmonic filtering, and a low noise amplifier (LNA) with bypass mode, for equipment manufacturers seeking to adjust receive sensitivity. The receive chain provides 12.5dB of typical gain with only 12mA of current and an excellent noise figure of 2.5dB. Separate Rx/Tx 50 Ohm ports simplify matching and provide input and output signals for both the
