Ultralinear Wireless Amplifiers Using Low Cost Building Blocks Phoenix Microwave Telford, PA Linear power amplifiers (LPA) play a very important role in high performance wireless base stations. Modern multicarrier LPAs improve cell site performance and capacity significantly. Older base station equipment used single channels, each amplified individually using high...

Miniature, Low Noise Cryogenic Amplifiers MITEQ Inc. Hauppauge, NY The ability to cause improvement in a GaAs amplifier's noise figure performance by decreasing the base plate temperature has been common knowledge for many years. Various industries and disciplines such as radio astronomy and satellite communications have taken advantage of...

An Ultralinear Amplifier for PCS Applications Stealth Microwave, a division of SSB Technologies Inc. Trenton, NJ As PCSs are being deployed, many service providers are discovering that conventional base stations do not always provide satisfactory service over the entire cell area. This deficiency typically is caused by two factors:...

Self-aligning Coaxial PCB Connectors Applied Engineering Products (AEP) New Haven, CT One of the more common problems faced by designers of RF and microwave equipment who incorporate multiple PCBs is connecting the boards directly together so that the RF signals are transmitted properly between PCBs. This problem occurs because...
