A high-yield monolithic X-band four bit phase-shifter
A key element in a GaAs MMIC Transmit/Receive module for active Phased-array application is the phase-shifter needed for the electronic beam steering; because of the circuit complexity and usually large chip size the technological and electrical yield must be maximized. In the present work the design, realisation and performance of an X-band, four-bit phase shifter, using a high-yield technology and a tolerant electric circuit are described
Packaged X-band T/R module for active phased array radar applications
In this article we describe a global design approach of an X-band Tx/Rx module which, by means of a Multi Chip Module (MCM) technique, includes in a single package the different microwave functions (4-bit phase-shifter, low-noise amplifier, power amplifier, switching control circuits), the thin film interconnections, the bias circuits, the driver circuits (Si ICs) and the switching MOS
