TriQuint Semiconductor Introduces Two Power Amplifiers for 3.5 GHz WiMAX and BWA Transmit Applications

TriQuint HFET Device and Low-Cost SMT Package Technologies Provide High Performance Linear Power for WiMAX Applications

RICHARDSON, Texas & HILLSBORO, Ore.--(BUSINESS WIRE)--June 15, 2005--TriQuint Semiconductor, Inc. (Nasdaq:TQNT) today announced the introduction of two new amplifiers for broadband wireless access (BWA), 802.16 (WiMAX) and general S-Band high power amplifier applications. The products' high performance, simplified use and highly competitive pricing set them apart in today's broadband marketplace.

The two new amplifiers provide a variety of performance advantages, including instantaneous bandwidth of 200 MHz across any segment of the 3.3 to 3.9 GHz band with simple PCB layout and two external components. While designed to support the stringent linearity requirements of multi-carrier applications, both devices are also capable of delivering high saturated power and PAE. The SMT-style package incorporates internal partial matching to simplify PCB design and a high thermal conductivity copper alloy base to maximize heat removal from the amplifier.

The TGA2923-SG is a 10W power amplifier optimized for 3.5GHz Broadband Wireless Access (BWA) and WiMAX (802.16-2004) applications. The TGA2923 can be matched for approximately 200MHz instantaneous bandwidth in the 3.3 - 3.9GHz frequency band with only two additional external components. The TGA2923 is suitable for both BWA base station (BTS) and subscriber station (SS) applications as well as high power, high PAE S-Band applications. In a typical 3.4 - 3.6GHz BWA application, the TGA2923 delivers 9dB power gain, 10W Pout, and an IMD3 level of -50dBc at 28dBm SCL. Typical linear power of greater than 30dBm @ 2.5 percent EVM can be achieved when tested with a multi-carrier OFDM type input waveform.

The TGA2925-SG is a 5.6W power amplifier optimized for the 3.5 GHz BTS or SS wireless equipment market. It is also appropriate for high power, high PAE S-Band applications. Like the TGA2923, only two external components are required for approximately 200MHz instantaneous bandwidth in the 3.3 to 3.9 GHz range. Typical performance at 3.5 GHz will produce 11 dB nominal gain, 37.5 dBm Pout, and an IMD3 level of -50 dBc @ 24 dBm SCL. Linear output power of greater than 29 dBm results in an EVM of less than 2.5 percent with a multi-carrier OFDM type input waveform.

"TriQuint is committed to providing a full line of RF components for BWA and WiMAX applications. These markets are cost sensitive, and TriQuint is ready with high performance products that are easy to use and cost effective for the manufacturer. The new components further expand our existing line-up of discrete HPA products for the 2.5GHz, 3.5GHz and 5.8GHz frequency bands, and soon-to-be-released MMIC PA/Drivers," said TriQuint's Broadband Products Marketing Director, Dan Green.

Both devices are fabricated using TriQuint's proven 0.5-micron gate length, HFET process which enables world class electrical performance and increased environmental robustness under the most demanding operating conditions. Both parts are offered in a molded 2-lead, SMT-style package that is lead-free and RoHS compliant.
