“…Additionally, the high gain of the CB topology at mm-wave frequencies makes it a suitable core for PA cells. The power performance superiority of the CB configuration over CE DHBTs appears to confirm the analysis of Qin et al [23]. Whereas InP/GaAsSb CB DHBTs perform better than CE devices for low P IN (and conversely for high P IN , as for SiGe HBTs in [23]), InP/GaInAsSb CB DHBTs are superior to CE devices for all input power levels (Fig.…”

We report the 94 GHz large-signal load-pull performance of (0.3 × 9) μm 2 InP/Ga(In)AsSb double heterojunction bipolar transistors (DHBTs) in the common-emitter (CE) and common-base (CB) configurations. Both configurations were implemented side-by-side on either 20-nm-thick graded GaAsSbor GaInAsSb-base layers. A measured record saturated output power P OUT,SAT = 14.5 dBm with a corresponding power density 10.4 mW/μm 2 were achieved in the GaInAsSb-base CB configuration. The performance follows from i) the higher power gain in the CB topology and, ii) the superior BV CEO and BV CBO breakdown voltages obtained with the quaternary base which allow degradation-free operation at higher voltages. Load-pull contours show a combination of high output power and power gain in the proximity of 50 for a wide range of load impedances. In contrast, CB InP/GaAsSb DHBTs deliver P OUT,SAT = 10.6 dBm and 4.3 mW/μm 2 . For all devices considered here, CB operation improves transistor robustness against high-power device degradation. The present work provides the first report on the power performance of quaternary InP/GaInAsSb DHBTs in CE/CB topologies, with comparison to ternary InP/GaAsSb DHBTs.INDEX TERMS InP/Ga(In)AsSb, double heterojunction bipolar transistors (DHBTs), common-emitter (CE), common-base (CB), load-pull measurements, maximum output power, power gain, power density.This article has been accepted for inclusion in a future issue of this journal.

“…Because there is a need in technology to amplify electrical signals, i.e. to obtain on a load circuit higher power signals but identical in form of time variation with those of low power available, amplifiers are used [9][10][11][12][13][14].

Because of the large number of parameters that interact in their function, determining dynamic regime parameters as well as the mode of function of amplifying stages is an extremely complex problem. This paper describes a LabVIEW application for studying the functioning of an ampli-fier in various connections. The user selects the generator's parameters, the type of connection and its parameters, as well as the electric charge characteristics. The application can determine both the stage characteristics and the Bode characteristics. The amplifier's stability zone, as well as its gain and phase, are determined based on these characteristics. An important advantage of this application is that the design of the amplifier stage can be made starting from some param-eters that the amplifier can establish, from which the values of components can be determined. In order to validate the simulation results using the LabVIEW application, a specialized program Multisim was used, as well as experimental measurements using the Electronics Explorer Board. Both Multisim and Electronics Explorer Board can determine Bode characteristics. In both simu-lations and experimental amplifiers, the same schemes with the same transistor was used. The application can be used for educational purposes as well as to design the amplifier's stage to achieve specific parameters.
