TriQuint Offers New Ultra-Wideband, Packaged MMIC Amplifiers with Industry-Leading Bandwidth Performance.

HILLSBORO, Ore. & RICHARDSON, Texas -- New Products Target Optical, Military, Homeland Security, Digital Radio and Test Applications

TriQuint Semiconductor, Inc. (Nasdaq:TQNT) has introduced new high-performance products designed for the demanding bandwidth needs of optical networks, point-to-point radio, military communications, instrumentation and Homeland Security applications. The new products offer exceptional electrical performance and the ruggedness required by battlefield and high-demand industrial applications. The product releases will be announced at the Optical Society of America's annual OFC trade show in Anaheim, CA (6th-11th March 2005).

Three Low-Cost Ultra Wideband MMICs (DC-40 GHz):

--The TGA4830-EPU (MMIC) sets a new record for bandwidth performance from DC to 45 GHz offering medium power and a low noise figure, plus adjustable gain. It features a +11.5 dBm one-dB compression point with 13 dB of gain, while delivering a 3.2 dB typical noise figure. Also offering 20 dB of AGC range, the TGA4830-EPU is well suited for optical modulator driver and instrumentation applications and for use in electronic warfare systems including radar warning receivers, countermeasures, decoys, jammers and phased-array systems. Typical input and output return losses are 15 dB and both RF ports are DC coupled, enabling the user to customize system corner frequencies.

--The new TGA4832-EPU is also an ultra-wideband device. This medium power wideband AGC amplifier operates from DC to 35 GHz. It offers a +18 dBm 1 dB compression point, with small signal gain of 12 dB and a 3 dB AGC range. The TGA4832-EPU is an excellent choice for 40 Gb/s NRZ optical modulator driver applications and is well suited for instrumentation. Other applications include electronic warfare systems such as radar warning receivers, countermeasures, decoys, jammers and phased-array systems. In addition, the TGA4832 may also be used as a predriver or a receive gain block. A data sheet for this product is available at: http://www.triquint.com/docs/TGA4832/TGA4832-EPU.pdf

--The TGA4036 is a low cost, compact medium power amplifier MMIC for wideband applications. Covering the 19 to 36 GHz band, it is ideal for low cost, emerging communication market applications such as point-to-point, point-to-multipoint radio and satellite communication systems or instrumentation. Performance includes 20 dB small signal gain, saturated output power of +22 dBm, and 8 dB input/output return loss.

Four Packaged MMICs offering multi-band performance:

--The TGA2509-EPU-FL is a wideband high power amplifier offering +29 dBm, 1 dB compression point performance. It is offered in a 10-lead flanged package, which exhibits minimal performance degradation and operates over the 2-20 GHz frequency range. The TGA2509 provides 15 dB of small signal gain with 6 dB input and 9 dB output return losses. It is particularly well suited for wideband electronic warfare systems, test equipment, VSAT terminals and digital radio applications. The flange lead package has a copper alloy base for optimal thermal conductivity. Evaluation boards are available by contacting your local TriQuint representative. A data sheet for this product is available at: http://www.triquint.com/docs/TGA2509/TGA2509-EPU-FL.pdf

--The TGA2513-SM is a compact LNA/gain block packaged MMIC amplifier, which operates over the 2-20 GHz frequency range. Offering 17 dB nominal gain, it incorporates a gain adjustment of greater than 30 dB using Gate 2 voltage input. The one dB compression point performance is +16 dBm and the typical noise figure is 2.5 dB midband. The TGA2513-SM is available in a 12 lead 4x4 QFN style package. Input return loss is at -12 dB typical and output return loss is -10 dB typical. It is suited for a variety of wideband electronic warfare systems such as radar warning receivers, counter measures, decoys, jammers and phased array systems. Evaluation boards are available by contacting your local TriQuint representative. A data sheet for this product is available at: http://www.triquint.com/docs/TGA2513/TGA2513-SM.pdf

--The TGA2503-SM is a Ku-band packaged power amplifier ideally suited for the VSAT ground terminal market and for point-to-point radio applications. This new PA operates from 12.5-16 GHz and typically provides 32 dBm midband saturated output power with typical small signal gain of 32 dB. The TGA2503-SM is available in a 24 lead 4x4 QFN style package. Evaluation boards for this product are available upon request from your local TriQuint representative. A data sheet for this product is available at: http://www.triquint.com/docs/TGA2503/TGA2503-SM.pdf

--The TGA2512-SM is a packaged X-band balanced LNA with AGC amplifier for electronic warfare, counter measures and radar receiver or driver amplifier applications. This new product provides excellent noise performance with a typical midband noise figure of 2.3 dB, and high gain: 25 dB from 4-14 GHz. This product is designed for maximum ease of use and can handle up to 21 dBm input power with solid reliability. The part's built-in gain control provides 15 dB of typical control range. The new LNA can be used in self-biased mode, with a single +5V supply connection, or in gate-biased mode for current control in a given application. It is available in a 12 lead 4x4 QFN style package. Evaluation boards are available from TriQuint representatives.
