Integrated power detector, biasing, harmonic filtering, and enable pin
Both parts are available now in production quantities. Pricing for 5000 pieces begins at $1.26 each for RFPA5200 and $2.64 each for RFPA5201.
RFMD reveals 5GHz WiFi module for 802.11ac
The RFFM4501E is based on the firm’s InGaP HBT and GaAs pHEMT technologies and is designed for notebook and mobile equipment devices
RF Micro Devices has introduced the highly- integrated RFFM4501E front end module (FEM) for 802.11ac notebook and mobile equipment applications.
The firm’s latest WiFi FEM meets or exceeds the system requirements for 802.11ac connectivity in the 5.150GHz - 5.850GHz frequency band and is optimised to support multiple applications. These include notebooks, mobile routers, and low-power customer premises systems.
The RFFM4501E integrates a +17.5dBm (80MHz 146

RFMD`s Kobayashi awarded 2013 IEEE Fellow
Kobayashi has been acknowledged for his work in gallium arsenide (GaAs) MMIC and indium phosphide (InP) technology
RFMD Fellow Kevin W. Kobayashi has been named a Fellow of the Institute of Electrical and Electronics Engineers (IEEE) by the IEEE Board of Directors.
The IEEE grade of Fellow was conferred on Kobayashi in recognition for his contributions to monolithic microwave integrated circuits (MMICs).
The IEEE is one of the world’s largest professional associations for the advancement of technology.
Less than one-tenth of one percent of the total IEEE voting membership is recognised each year by the IEEE Board of Directors for elevation to IEEE Fellow.
Bob Bruggeworth, CEO and president of RFMD, says, “Kevin is an outstanding engineer with an extraordinary record of accomplishments. His extensive industry knowledge and deep expertise across multiple technologies are valuable assets to RFMD and to our customers. We stand with
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 transmit and receive paths.
The RFFM4501E is optimised to mate with the 802.11ac chipset of a leading semiconductor company.
The ultra-small form factor (3mm x 3mm x 1.1mm) and high level of integration of the RFFM4501E shrink the product footprint, reduce external component count, minimise assembly costs, speed time-to-market.
