Mitsubishi Electric Announces Sale of Switchable Power Amplifier Module for WCDMA Applications.TOKYO -- Mitsubishi Electric Corporation (TOKYO:6503) (President and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. : Setsuhiro Shimomura) announced today it has developed an InGaP HBT HBT Heterojunction Bipolar Transistor HBT HyCult Biotechnology (Uden, The Netherlands) HBT Hanbury-Brown-Twiss (interferometer) HBT Herring Bone Twill HBT Heflex Bioengineering Test 1 switchable power amplifier for WCDMA (Wideband CDMA) A 3G high-speed digital data service provided by cellular carriers that use the TDMA or GSM technology worldwide, including AT&T (formerly Cingular) and T-Mobile in the U.S. 2 used in mobile handset terminals. The amplifier module shows improved efficiency at low to mid power output, and also eliminates the need for external peripheral components, reducing the size of mobile handsets. Sample shipments will begin in February of 2007. 1Indium Gallium Phosphide Indium gallium phosphide (InGaP) is a semiconductor composed of indium, gallium and phosphorus. It is used in high-power and high-frequency electronics because of its superior electron velocity with respect to the more common semiconductors silicon and gallium arsenide. Hetero-junction Bipolar Transistor: a high frequency device with excellent high operation efficiency used in mobile handset terminals, etc. 2Wide-band Code Division Multiple Access: a broadband and code division multiple access type of mobile digital communications [TABLE OMITTED] Aim of Sale With the increasing high function and multi-band/mode operations in cellular handsets in recent years, developers have been trying to reduce the size and increasing number of necessary components to keep terminals small. To secure talk time, typical WCDMA power amplifiers need an external DC/DC converter to lower operating voltage and improve efficiency at low and mid range output when operation repetitions are frequent. We have developed a power amplifier module that does not need an external DC/DC converter by using 2 chain amplifiers that can switch to respond to different outputs, guaranteeing efficiency during low and medium output. This improves efficiency, and secures talk time while also reducing size of mobile handset terminals. Product Characteristics 1) Increased talking time We created a module with amplifiers for large and medium to small levels of output, and employed a system that can switch between amplifiers according to output. Power added efficiency is 40% during high output (27 dBm), 24% during medium output (16 dBm), and 7% during low output (8 dBm). Medium range power added efficiency, in particular, is the highest in the industry, and does not need the typically required external DC/DC converter to improve efficiency, extending talk time. 2) Reduced peripheral components, smaller mobile handset terminals We developed a module with the same dimensions (4x4x1.2 mm) as our previous WCDMA module (BA01231/BA01232) by using Monolithic Microwave Integrated Circuit MMICs, or Monolithic Microwave Integrated Circuits, are a type of integrated circuit (IC) devices that operate at microwave frequencies (1 GHz to 300 GHz). They typically perform functions such as microwave mixing, power amplification, low noise amplification, and high (MMIC (Monolithic Microwave IC) An integrated circuit used in high-frequency applications such as mobile phones. Also known as "monolithic microwave/millimeter-wave IC," MMICs combine transistors and passive devices (resistors, capacitors, etc. ) and our own mobile handset module design technology to internally mount the bias circuitry reference voltage generator and two types of power amplifiers. This keeps mobile handsets small as reference voltage generators are typically an external component. Future Developments In fall of 2007, we plan to continue the release of switchable power amplifier modules that respond to Band9 (1752.4-1782.6 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. ), Band2 (1850-1910 MHz), and Band5 (824-849 MHz) bandwidths.
