High Efficiency L-Band GaN Power Amplifier

This article illustrates the design and development of a 60 W pulsed Class F power amplifier over the frequency range of 1.25 GHz ± 50 MHz. The power amplifier has been designed and fabricated using a GaN HEMT transistor. This amplifier shows a competi...
The rapid growth of wireless communications, as well as space-borne systems, leads to the increasing demand of low power, high efficiency systems. High efficiency is the prime requirement for any space-qualified transmitter or wireless communication systems. Higher efficiency means greater output power with reduced power dissipation. Achieving higher efficiency...

Direct Measurement-based Modeling of Ultra-low Resistance Passive Components

This article presents a methodology for modeling the resistance of MIM capacitors, directly from measured S-parameters, using an ultra-low impedance measurement known as the “S21-shunt” technique. It leverages from the work previously introd...
Metal-insulator-metal (MIM) capacitors, (MIM caps) have played a vital role in the design of a wide variety of MMIC circuits, particularly where low loss/high-Q is a critical design requirement. Because of their ease of fabrication, they can be found in the design kits of both silicon and compound semiconductor...

Design of V-Band Millimeter-wave CMOS Low Noise Amplifier

A V-Band millimeter-wave CMOS low noise amplifier (LNA) fabricated with the 0.13 mm process is presented. A three-stage cascaded common source structure is adopted. The measurement results of the fabricated LNA show the peak performance at 50 GHz exhib...
In recent years, the 7 GHz of contiguous bandwidth have been opened for unlicensed use at millimeter-wave frequencies around 60 GHz (known as V-Band) in the US and Japan. High rate wireless communication technology operating at millimeter-wave frequencies has been an interesting topic with various applications and tremendous potentials....
