The 1/f additive phase noise of one-port injection-locked oscillators is experimentally characterized and analyzed using a simple analytic model based on the generalized Kurokawa theory. To verify prediction proposed, two negative-conductance transmission line pHEMT operating at 2.4828 GHz 2.485 were designed fabricated. A new configuration for integrating an measurement system with large signa...

This paper presents the design of a dual-band power amplifier (PA) featuring similar performance at 28 GHz and 38 GHz. In new radio (NR) fifth generation (5G) communication system, inter-band carrier aggregation technique is commonly adopted for data rate enhancement. such configuration, operation both bands 5G frequency range 2 (FR2) spectrum often necessary. The stacked-FET topology was mitig...

This article presents an on-chip state-adjustable 8 GHz~12 GHz low-noise amplifier (LNA). It has two characteristics. First, improved current reuse topology is proposed. By connecting a small capacitor in parallel with the drain of first-stage transistor, bandwidth expanded and in-band flatness improved. Second, innovative adaptive bias circuit designed to cope influence temperature process on ...

In this paper, a simple non-linear analytical charge control model for the DC and microwave characteristics of AlGaN/GaN MODFET is presented. The effect of parasitic resistances s R and d R is also incorporated. The model has also been extended to obtain the expressions for transconductance, drain conductance and cut-off frequency of the device. The model predicts a high transconductance of 502...

Traditionally a majority of the commercial satellite communications systems have been fixed repeaters at C-band and Ku-band. The satellite industry is presently undergoing significant changes in the types of systems that are being fielded. New low earth orbit and geo stationary mobile systems have large numbers of flexible beams at either L-band or S-band through the use of large phased array a...
