J&R Microwave Solutions Successfully Designs Complex Active Power Splitter MMIC With AWR Software

An active power divider has been designed to ease the extended dynamic range of the detector log video amplifier (EDLVA) system's complexity by replacing the low noise amplifier (LNA) and the passive power divider with a single component. For extra-wide bandwidth, high gain and post-fabrication gain control, the selection of a cascade configuration was made. Therefore key challenges of the design have been accommodating a pair of 10 FETs in a cascade configuration along with presenting the RF/DC networks in a compact layout, and yet achieving the targeted performances.
