Mon, 08/01/2005 - 6:20am

TriQuint Semiconductor introduces a high power amplifier for millimeter wave digital radio and satellite ground terminal applications. This packaged device allows subsystem integrators to simplify assembly and alignment, thereby decreasing product complexity and cost. The product is part of a six-member family of HPAs and LNAs.

The TGA4509-SM is a high performance power amplifier in a low parasitic package suited for use in 27 to 31 GHz transmit chains found in VSAT, point-to-point and point-to-multipoint radio applications. The device is also physically small, which allows direct integration with other electronic circuitry elements, minimizing performance impact. Packaging is lead-free, RoHS-compliant, offering customers an environmentally friendly solution with substantial cost and assembly advantages.




The TGA4509-SM HPA's technical specifications:

• Operating Frequency: 28 to 31 GHz

• P1dB Output power: +30 dBm

• 19 dB nominal gain • Bias conditions: Vd = 6 V, Idq = 420 mA (Id = 800mA under RF drive)

• Compact 4x4 QFN-20 package

• 100% RF tested in package form

• Datasheet available at:

The TGA4509-SM provides a combination of power amplifier performance in a convenient surface mount QFN package at Ka-band frequencies. The typical performance of the device is shown in the plot below. The TGA4509-SM compliments the company's power amplifiers (p/n TGA4905-CP and TGA4915-CP). TriQuint provides a complete transmit solution for these millimeter wave applications. All devices are fabricated using TriQuint's MMW pHEMT processes.
