Active filter structures are proposed using a low-frequency transversal and recursive approach. Separate studies of the different functional blocks lead to the design of nontunable and tunable original structures for which we present both simulated a

A new sampling phase detector monolithic microwave integrated circuit (MMIC) using a standard 0.18-/spl mu/m GaAs technology has been designed and tested. The authors emphasize that commutation time has to be taken into account rather than pulse dura

A monolithic Ku-band 6-bit digital attenuator with on chip serial to parallel converter has been developed. The integration of a digital part reduces the bias circuitry and opens the way to new circuits combining digital and analog functions. The cir

This article deals with a multicellular approach for high-order monolithic active recursive filter design. The transfer function results from a cascade association of first-order recursive cells, each characterizing a single pole. We illustrate our a

This article deals with the improvement of the noise figure for three topologies of microwave active recursive filters. We show how, using a noise wave formalism , the noise factor of these filters can be effectively minimized by using appropriate un

In this article, two active filters in the X-band, using low frequency transversal and recursive principles are presented. Previously implemented in hybrid technology, those two structures are developed here using MMIC technology. In a first step, st

In the past twenty years a considerable amount of work has been done on microwave circuit integration, mainly using GaAs material. MMIC's were finally introduced to the space-borne equipment in the early 90s. They are now clearly unavoidable and many

A very aggressive policy has been set up in the early 1990s to introduce MMIC in space equipment in ALCATEL Space Industries. The first step was to choose preferred suppliers able to produce high reliability low level or power MMIC's up to Ku band ev
