Introduction This tutorial is intended to guide the user through the stages of a basic low noise amplifier design and optimization, with a goal of first-pass fabricated design success. This will be accomplished by providing the user with a project tutorial, starting with the design process and ending with a comparison between the software simulations and the model performances. This example use...

In this paper, to substitute the existing TWTA(Travailing Wave Tube Amplifier) component in small radar system, we developed Ku band SSPA(Solid-State Power based on fabrication of power MMIC (Monolithic Microwave Integrated Circuit) chips. For development 500 W SSPA, 40 W-grade was designed by ADS(Advanced Design System) at Keysight company with UMS GH015 library, and processed foundry service....

The Doherty power amplifier (DPA) is one of the most popular power amplifier architectures for obtaining high average efficiency for modern communication signals with high peak-to-average power ratios (PAPR). However, the DPA suffers from often having narrowband performance which limits its capabilities in wideband and/or multi-standard microwave and radio frequency applications. In this thesis...

Many modern EW systems require low noise receivers capable of withstanding wide input power variations over a multioctave bandwidth. These receivers are necessary to protect sensitive components from RF overdrive or to remove AM modulation from incoming signals. Further, multichannel system designs and proximity to the receiver antenna generate requirements for low power and small package size....

This paper presents a high-power microwave oscillator using recursive balanced amplification technique. The proposed architecture is configured by power amplifier (BPA) with class-AB operation and two feedback networks. Each circuit consists of phase shifter high-Q bandpass filter (BPF). BPA an input hybrid coupler (IHC) output (OHC) to divide recombine signals amplified through amplifiers (PAs...

Microwave amplifiers find applications in almost all devices working at high frequencies and thus find applications in communication systems, satellites as also radars and navigations. It is thus very important for the students of electronics and its allied branches to have an in depth knowledge about the design of such amplifiers. The design of microwave amplifiers is a vast subject, and is by...

Analysis and simulation the existence of electrical memory effects and thermal memory effects in different spacing two-tone input signal and modulated signal source through advanced design system (ADS) software simulation, respectively. Built thermal memory effects compensation circuit in the ADS environment to confirm the compensation circuit has a good compensation to the thermal memory effec...
