1 WATT C BAND AMPLIFIER C.GOLDZTEJN*, ABSTRACT: This article describes the design and realization of a power amplifier in C Band used for a MMIC front-end transmitter. Its output power is equal to 30 dBm (1 watt) at 1 dB compression with a gain over 23 dB between 5.9 and 8.5 Ghz. The chip size is 2 x 3.5 mm2. D.FAYOL**, C.SIMON**, M.ANDRE** 

30 GHz SOLID STATE POWER AMPLIFIER FOB SMALL BARTH STATIONS P. GaJante - G. Carpentiere C*) ABSTRACT This paper describes a 30 GHz Solid State Power Amplifier (SSP A) to be used in small earth stations operating with 30/20 GHz satellite payloads and emploYing antennas not larger than one meter. The SSP A is foreseen to be mounted directly behind the antenna feed in the front-end subsystem and i

AN ULTRA FLAT GAIN AMPLIFIER FOR SPACE APPLICATIONS MICHEL SOULARD, FLORENCE LABARRE, NATHALIE PICHON * MONIQUE ANDRE ** ABSTRACT The aim of this paper is to present the design and performances of an Ultra Flat Gain Amplifier for space applications. An MMIC implementation has been realized using THOMSON foundry service. 12 dB gain is obtained with a very low ripple lower than 0.1 dBpp over 10.7 -

KU-BAND AMPLIFIERS AND MODULES FOR SPACE APPLICATIONS G.Eggers*, D.Leistner* and R.Kohl* ABSTRACT A number of components and modules for space applications are developed and realised on Alumina and Aluminum-Nitride substrates using thinfilm technology. At Ku-band frequencies, Low Noise Amplifiers (LNA), Power Amplifiers, and Beam Forming Networks (BFN) are given as typical representatives. New c

Accurate Prediction ofTnmsimp-dances and Equivalent Input Noise C11ITeDt ensities of Tuned Optical Receiver Front Ends D QiDg Zhong Uu Abstmct Novel analytical expressions have been derived for calculating transimpedances and equivalent input noise current densities of five tuned optical receiver front ends based on PIN diode and MESFETs or HEMTs.

THE ARTIFICIAL INDIRECT TRANSMISSION LINE AS AN OP'rICAL MODULA'l'OR C S Aitchison ABSTRACT This paper considers the use of an artificial transmission line, rather than a true transmission line for the provision of the interactive region of an electro-optic modulator on material such as Lithium Niobate. The advantage is that equality of phase velocity of optical and microwave modulating signal

LASER TUNING OF A PLANAR ACTIVE BAND-PASS FILTER USING MESFETs YukioYamamoto., Jenshan Lin.. and Tatsuo Itoh.. ABSTRACT The MESFET controlled active band-pass filter is examined using a semiconductor laser for tuning. The filter is basically end coupled microstrip band-pass filter. The series tank circuit of the filter includes a tuning MESFET. The cover of the MESFET element is removed and the

A MMIC BASED NEW LIGHTW AVE-MICROW AVE PHASE DETECTOR Tibor Berceli* ABSIRAcr The paper presents a new lightwave-microwave phase detector which can be implemented into a MMIC construction. The new phase detector is rather simple and exhibits a good performance. Previously, indirect phase detection has been presented containing PIN photodiodes and a microstrip hybrid. Neither the PIN diodes, nor t

OPTICALLY CONTROLLED ACTIVE INDUCTOR W. D. Jemison*, P. R. Herczfeld* and A. Madjar* ABSIRAcr An optically controlled MMIC compatible active inductor is demonstrated. The device is realized by a MESFET based circuit configuration which exhibits a shunt inductive characteristic which may be tuned by direct illumination of one of the circuit's MESFETs. The optically tuned active inductor may then b
