چکیده

In this paper the design and a complete characterization of an InP/InGaAs single heterojunction bipolar (SHBT) mm-wave amplifier is described. The circuit is designed for the 60 GHz band allocated for wireless LAN and mobile communications. The amplifier achieves a gain of 20 dB from 50 GHz to 70 GHz. Beside S-parameter noise and gain compression measurements are presented. No comparable HBT amplifier at 60 GHz could be found in literature.

InP-based Complementary HBT Amplifiers for use in Communication Systems

This paper addresses a method to improve the linearity characteristics of power amplifiers by developing a PNP HBT technology and combining the PNP HBTs with NPN HBTs in a push-pull amplifier. InP-based PNP HBTs were fabricated with hfe > 30, BVECO = 5.6 , and fT and fmax of 11 and 31 GHz, respectively, which is the best reported for InAlAs/InGaAs PNP HBTs. Common-collector push-pull amplifiers...

SiGe HBT wideband amplifier for millimeter wave applications

A wideband amplifier up to 50 GHz has been implemented in a 0.25 μm, 200 GHz f t SiGe BiCMOS technology. Die size was 0.7×0.73 mm. The two-stage design achieves more than 11 dB gain over the whole 20 to 50 GHz band. Gain maximum was 14.2 dB at 47.5 GHz. Noise figure was lower than 9 dB up to 34 GHz and a current of 30 mA was drawn from a 4 V supply. To the author’s best knowledge this is the hi...

112-GHz, 157-GHz, and 180-GHz InP HEMT Traveling-Wave Amplifiers - Microwave Theory and Techniques, IEEE Transactions on

We report traveling-wave amplifiers having 1–112 GHz bandwidth with 7 dB gain, and 1–157 GHz bandwidth with 5 dB gain. A third amplifier exhibited 5 dB gain and a 180GHz high-frequency cutoff. The amplifiers were fabricated in a 0.1m gate length InGaAs/InAlAs HEMT MIMIC technology. The use of gate-line capacitive-division, cascode gain cells and low-loss elevated coplanar waveguide lines have y...

A 155=GHz Monolithic Low Noise Amplifier

This paper presents the design, fabrication and performance of a three-stage 155GHz monolithic low noise amplifier (LNA) using 0.1 -pm pseudomorphic (PM) InAIAs/InGaAs/InP HEMT technology. This amplifier exhibits a measured small signal gain of 12 dB at 155 GHz, and more than 10 dB gain from 151 to 156 GHz. When this amplifier is biased for low noise figure, a noise figure of 5.1 dB with associ...

A 46 GHz Bandwidth Monolithic InP/InGaAs PIN/SHBT-Photoreceiver

A InGaAs PIN-photodetector and a lumped SHBT-transimpedance-preamplifier have been mono-lithically integrated and characterized. The preamlifier achieves a transimpedance gain of 44:6 dB (170) and the optical/electrical ?3dB-bandwidth of the entire receiver is 46 GH z. This is, to the best of our knowledge, the highest bandwidth for any HBT based photoreceiver reported to date.
