A 44 GHz 0.18μm CMOS Superharmonic Frequency Divider
2007 Edition, June 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a low power 44 GHz 0.18 μm CMOS superharmonic frequency divider. The superharmonic locking technique is proposed to perform direct divide-by-four operation. The integrated circuit was implemented in the commercial 0...

A 44-GHz HEMT doubler/amplifier chain
1990 Edition, January 1, 1990 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A 44-GHz doubler was designed and fabricated using 100- mu *0.15- mu m InGaAs high-electron-mobility transistor (HEMT) and microwave integrated circuit (MIC) circuit. The doubler shows a minimum conversion loss of 1.4 dB with 0.4-dBm output power and 1.6-dBm maximum...

Power HBT for 44 GHz operation
1993 Edition, January 1, 1993 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The GaAs based heterojunction bipolar transistor (HBT) has been evaluated as an amplifying device at 44 GHz. The device type measured is essentially identical to that used for power MMICs between 4 and 20 GHz. No ultra fine lithography, no special layer systems were necessary...

44 GHz Monolithic Low Noise Amplifier
1987 Edition, Volume 87, January 1, 1987 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The design, fabrication, and performance of a single-stage 44 GHz monolithic HEMT low noise amplifier are described. The chip includes a single heterojunction HEMT with matching and biasing circuits. Greater than 5 dB gain was measured from 43.5 to 45.5 GHz and...

44-GHz monolithic GaAs FET amplifier
1986 Edition, Volume 7, February 1, 1986 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Millimeter-wave monolithic GaAs FET amplifiers have been developed. These amplifiers were fabricated using FET's with MBE-grown active layers and electron-beam defined sub-half-micrometer gates. Source groundings are provided through very low inductance via holes. The single-stage amplifier has...

A 44 GHz Quadrature Traveling Wave Oscillator
2013 Edition, January 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a technique for quadrature phase generation in an LC oscillator by sharing a single turn inductor between a pair of oscillators. This special structure of the inductor cancels the magnetic flux within the loop, and thereby allows placement of other...

44 GHz monolithic HEMT downconverter
1990 Edition, January 1, 1990 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A systematic design, fabrication, and evaluation of a monolithic HEMT (high-electron-mobility transistor) downconverter is presented. The downconverter contains a three-stage low-noise amplifier (LNA), a single balanced mixer, and a two-stage post-amplifier (IF...

44 GHz hybrid HEMT power amplifiers
1989 Edition, January 1, 1989 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Doped-channel, 0.25- mu m-gate-length, InGaAs pseudomorphic HEMTs (high electron mobility transistors) have been developed which exhibit state-of-the-art power performance at millimeter-wave frequencies, with output power density of 0.93 W/mm and power-added efficiency of 41% at 44...

Planck-LFI 44 GHz back end module
2005 Edition, Volume 41, October 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This work describes the principle of operation, assembly and performance of one branch of the 44 GHz back end module (BEM) for the Planck low frequency instrument (LFI). This subsystem constitutes a fully representative branch of the qualification-model version (QM). It...

High IP3-low DC power 44 GHz InP-HBT amplifier
1998 Edition, January 1, 1998 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper reports on what is believed to be the highest IP3/P/sub DC/ power linearity figure of merit (LFOM) achieved from a MMIC amplifier at millimeter-wave frequencies. The 44 GHz amplifier is based on an InP HBT technology with f/sub T/s and f/sub max/s of 70...
