Abstract
An apparatus and method for building and operating of a YIG-based filter-attenuator module with closed-loop control. The module combines both signal filtering and amplitude control functions by utilizing an yttrium-iron-garnet (YIG) resonator. A technique for a closed-loop calibration and control also disclosed. This apparatus and method provides a cost effective harmonic rejection/amplitude control solution for microwave test-and-measurement instruments such as signal generators and spectrum analyzers.
