November 2007 [Devices & ICs] Designing MMIC Distributed Amplifiers Distributed amplifiers offer moderate to high gain over broad frequency ranges. They have been designed with transmission lines as input and output feeds for some time. An early paper (1948) by Bill Packard (co-founder of Hewlett-Packard Co.) even showed how to use vacuum tubes for amplification in a distributed design.1 As GaAs monolithic-microwave-integrated-circuit (MMIC) technology developed and different types of amplifiers were fabricated ... November 2006 [Devices & ICs] Design An MMIC LNA With GaAs PHEMTs Low-noise amplifiers (LNAs) are critical for extracting signals from noise in communications receivers. Other techniques are available for controlling noise in a system, including filtering and cryogenic cooling, but high-performance LNAs offer a proven, reliable means of managing communications system noise. What follows is an exploration into the design of a low-power (battery-operated) LNA operating at X-band (8 GHz). The design compares the use of GaAs PHEMT... July 2003 [Components] Convert Distributed MICs To MMICs Monolithic microwave integrated circuits (MMICs) offer considerable size and weight advantages over their microwave-integrated-circuit (MIC) counterparts. But realizing proven passive MIC components as MMIC designs can present a challenging set of... |
