Agilent Unveils Millimeter-wave and Microwave Monolithic ICs

2/20/2004 - Agilent Technologies Inc. (NYSE: A) announced the second group of ICs in its AMMC series of low-cost pHEMT (pseudomorphic high-electron-mobility transistor) millimeter-wave and microwave monolithic integrated circuits (MMICs). These devices are fabricated using a 0.15-micron gate length pHEMT process on six-inch wafers with similar performance and comparable connection-pad locations as Agilent's proven HMMC series ICs.

"These additions to Agilent's second-generation millimeter-wave MMIC family offer a combination of lower cost with excellent performance for communications, instrumentation and military systems," said Philip Gadd, worldwide marketing manager of Agilent's Wireless Semiconductor Division. "Equally important is our high-capacity production capability that allows us to deliver large production quantities with quick turnaround."

The AMMC-3041 is a double-balanced active mixer optimized for upconversion or downconversion applications in point-to-point radios, local multipoint distribution systems (LMDS) and satellite communications systems operating from 18 GHz to 42 GHz. It is fabricated using a suspended metal system to create a broadside-coupled balun structure that achieves exceptional bandwidth.

The AMMC-3040 is a similar mixer with a built-in local oscillator (LO) amplifier that can be used as either an upconverter or downconverter in 18 GHz to 36 GHz radio applications. The LO amplifier can be biased to function as a frequency multiplier to enable second harmonic mixing of the LO input.

The AMMC-5033 operates from 17.7 GHz to 32 GHz, and is primarily intended as a driver and output stage amplifier in 18 GHz, 23 GHz, 26 GHz, and 32 GHz point-to-point radio transmitters. At 25 GHz, it provides 27 dBm of linear output power (P-1dB) and 20 dB of small-signal gain, and includes 50-ohm input and output matching circuitry.

The AMMC-5618 is a two-stage 6 GHz to 20 GHz linear (class-A) amplifier that can be used as a driver or buffer in microwave communication systems and as a general-purpose gain block. A 50-ohm matching circuit is provided at both the RF input and output.

The AMMC-5620 is a wideband amplifier designed for medium output power and high gain over the 6 GHz to 20 GHz range. It provides a typical 19 dB gain and 15 dBm linear output power at 20 GHz.
