Renesas Technology Introduces High-Performance SiGe MMIC: a Dual-Band (2.4GHz/5GHz) Wireless-LAN Power Amplifier.High-Gain Device for 802.11a/b/g LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. and MIMO (Multiple Input/Multiple Output) Pronounced "my-mo," it is the use of multiple transmitters and receivers (multiple antennas) on wireless devices for improved performance. Terminals Has the Industry's Lowest Current Dissipation Level of 130mA for 2.4GHz Operation SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- Renesas Technology Renesas Technology Corporation (ルネサス テクノロジ| America, Inc. today announced the high-performance HA31010, a 2.4GHz/5GHz dual-band SiGe 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. (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 ) power amplifier Power amplifier The final stage in multistage amplifiers, such as audio amplifiers and radio transmitters, designed to deliver appreciable power to the load. . The device uses less current and circuit board space, so it enables smaller, lower-power dual-band/triple-mode (IEEE-802.11a/b/g) and MIMO (Multiple-Input/Multiple-Output - 802.11n) wireless-LAN terminals. By incorporating two power amplifiers on a single chip Co one for the 2.4GHz band and another for the 5GHz band Co the HA31010 MMIC achieves a 4 mm x 4 mm mounting area A general locality where assigned forces of an amphibious or airborne operation, with their equipment, are assembled, prepared, and loaded in shipping and/or aircraft preparatory to an assault.

The device delivers high gain at the industry's lowest current dissipation level for a SiGe MMIC. Specifically, it achieves a 28dB power gain in the 2.4GHz band while consuming only 130mA, and a 24dB power gain in the 5GHz band while consuming just 160mA. An on-chip MOSFET-based switching circuit provides on/off control of the two amplifier circuits, simplifying band switching and transmit/receive implementation by eliminating the need for an external switching device. The HA31010 MMIC also incorporates an output power detector circuit. This feature simplifies the design of wireless LAN terminals that actively implement low power consumption. In such designs, the power detector serves as a sensor for the automatic output-power control function that maintains the minimum output power necessary for performing communication. Renesas uses an ultra-fine SiGe-CMOS process to manufacture the HA31010 chip, which allows a high level of integration. The transistor pattern and circuit-block layout are optimized to reduce parasitic capacitances and inductances that would otherwise degrade high-frequency characteristics. The chip is mounted in a small surface-mount, 24-pin WQFN0404 (Renesas package code) package that is totally lead-free. The package employs silver paste material for optimal die bonding reliability and conductivity, and Sn-Bi (stannum-bismuth) for package electrode plating. The HA31010 dual-band power amplifier is the second high-performance device Renesas has developed for wireless-LANs. The company entered this market in 2005 with the 5GHz HA31005 SiGe MMIC. Product development in SiGe technology is ongoing to meet the evolving needs of customers in global markets.
