Design and Implementation of the GHz-Band Wide(6 GHz~18 GHz) Linear Equalizer

Design Of 11 GHz Ku-Band Amplifier

Abstarct Amplification is one of the most basic and prevalent RF/Microwave circuit functions. This paper describes the design of an 11 GHz PHEMT ATF-36077 microwave amplifier. The amplifier is manually designed using conventional technique, Smith chart was used to do a matching of the input and output of the amplifier. A completed design of the amplifier was optimised using Hewlett-Packard Adva...

ALMA Band 5 (163-211 GHz) Sideband Separation Mixer Design

We present the design of ALMA Band 5 sideband separation mixer based on Niobium superconducting SIS junctions and first experimental results for the double side band mixer. In this mixer the LO injection circuitry is integrated on the mixer substrate using a microstrip line directional coupler with slot-line branches in the ground plane. The isolated port of the LO coupler is terminated by a wi...

PHOTONIC BAND GAP ACCELERATOR CAVITY DESIGN AT 90 GHz*

In previous work we have proposed utilizing Photonic Band Gap (PBG) structures as a new class of high-energy, high-intensity accelerator cavities. We have completed extensive MAFIA numerical calculations of multicell PBG structures, with each cell consisting of a square array of metal cylinders terminated by conducting sheets and surrounded by microwave absorber on the periphery. We find that o...

DESIGN OF MULTIBAND MICROSTRIP PATCH ANTENNA FOR WIRELESS 1 GHz TO 5 GHz BAND APPLICATIONS WITH MICROSTRIP LINE FEEDING TECHNIQUE

—In recent years many studies are concentrated on multiband micro strip antenna structures for important purposes in wireless communication systems, medical imaging, and radar sensor resolution. In this paper, we printed a square radiator patch on FR4 substrate material. The relative dielectric constant was 4.4, and the thickness of the substrate material was 1.6 mm. The patch was fed by a tran...
