Millimeter-wave band-pass filter using active matching principles

Abstract

A MMIC band-pass active filter at Ka-band using active matching devices have been successfully implemented employing 0.2 /spl mu/m-GaAs P-HEMT technology. A 5% measured relative bandwidth at millimeter frequencies have been achieved and validates the accuracy of the design methodology. In this contribution measured results have been reported with prime attention to low noise figure and power performance as it is necessary at the input of a receiver.
