Mimix Broadband, Inc. Introduces New Line of Ka-band Products, Including Power Amplifiers and Doubler

Power Amplifiers Achieve 1, 2 and 4-watts Psat; Use Doubler with Amplifiers to Simplify System Design

July 5, 2005, Houston, Texas – Mimix Broadband, Inc. introduces today a new line of Ka-band Gallium Arsenide (GaAs) monolithic microwave integrated circuit (MMIC) products, including power amplifiers and a doubler, covering the 27 to 34 GHz frequency bands, with the 30SPA0536 device achieving 36 dBm Psat. Using 0.15 micron gate length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, the new power amplifiers and doubler achieve the following performance levels:

The 30DBL0537 used in conjunction with the 30SPA0536 provides a perfect solution to highly integrated uplinks for commercial and defense applications, eliminating the need for a more complex heterodyne up-converter system design. The new amplifiers and doubler are well suited for wireless communications applications, such as millimeter-wave point-to-point radio, LMDS, Satcom and VSAT applications.

“These parts provide ‘state-of-the-art’ power levels at the Ka-band frequencies used for satellite uplinks, with good PAE and match, and exceptionally good lifetime, in 4-mil substrate thickness that facilitates handling at the die level,” stated Dr. Jim Harvey, CTO of Mimix Broadband, Inc. “In addition to providing these parts as die, Mimix is developing a range of packaged versions to facilitate low cost manufacture of Ka-band up-converters.”

Mimix performs 100% on-wafer RF, DC and output power testing on these products, as well as 100% visual inspection to MIL-STD-883 method 2010. The chips also have surface passivation to protect and provide rugged parts with backside via holes and gold metallization to allow either a conductive epoxy or eutectic solder die attach process.

Engineering samples are available today from stock, with production quantities being made available 6-8 weeks ARO. Technical support is also available from Mimix’s applications engineers at 281.988.4600. The datasheets and additional product information can be obtained from the Mimix Broadband website at www.mimixbroadband.com.
