Mimix Broadband, Inc. Introduces Two Stage GaAs MMIC Doubler That Can Be Used to Drive Fundamental Mixer Devices

Doubler well suited to drive Mimix's XR1002 receiver

March 29, 2004, Houston, Texas - Mimix Broadband, Inc. announced today the introduction of a Gallium Arsenide (GaAs) monolithic microwave integrated circuit (MMIC) two stage doubler that can be used to drive fundamental mixer devices. Using 0.15 micron gate length GaAs pseudomorphic high electron mobility transistor (pHEMT) device model technology, this doubler converts input signals in the 9 to 14 GHz frequency range to output signals in the 18 to 28 GHz frequency range. This device has +12 dBm output drive.

This doubler, identified as 12DBL0230, is ideal to drive Mimix's XR1002 receiver, and is well suited for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), SATCOM, and radar applications.

"By locating the doubler close to the receiver, the transmission losses incurred by the high frequency local oscillator signal can be minimized," stated Dr. Jim Harvey, CTO of Mimix Broadband, Inc. "The device also has application in up-converters or direct modulated FSK systems, where a 9 to 14 GHz signal needs to be doubled to the 18 to 28 GHz frequency range."

Mimix performs 100% on-wafer RF, DC and output power testing on the 12DBL0230, as well as 100% visual inspection to MIL-STD-883 method 2010. The chip also has surface passivation to protect and provide a rugged part 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, and production quantities are available 6-8 weeks ARO. Technical support is also available from Mimix's applications engineers at 281.988.4600. The 12DBL0230 datasheet and additional product information can be obtained from the Mimix Broadband website at www.mimixbroadband.com.
