  • Ultrawidband, Packaged MMIC Amplifiers
Mar 2005
TriQuint Semiconductor Inc.
ANAHEIM, Calif., March 8 -- TriQuint Semiconductor Inc. is introducing at OFC/NFOEC (booth 1463) this week three ultrawideband (microwave monolithic integrated circuit) MMIC amplifiers (DC-40 GHz) and four packaged MMICs offering multiband performance, designed for the demanding bandwidth needs of optical networks, point-to-point radio, military communications, instrumentation and homeland security applications.

The company said its new TGA4830-EPU MMIC sets a 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. 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, TriQuint said. 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 TGA4832-EPU 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 suitable for 40-Gb/s NRZ optical modulator driver applications and 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 be used as a predriver or a receive gain block.

The TGA4036 is a compact, medium-power MMIC amplifier for wideband applications. Covering the 19- to 36-GHz band, it is designed for 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.

TriQuint's four new packaged MMICs, offering multi-band performance, include:

The TGA2509-EPU-FL, 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 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.

The TGA2513-SM is a compact LNA/gain block packaged MMIC amplifier that 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. Typical input return loss is -12 dB, and typical output return loss is -10 dB. 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.

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

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. It has a typical midband noise figure of 2.3 dB, and high gain: 25 dB from 4-14 GHz. The product can handle up to 21 dBm input power with solid reliability; its 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.
