Designing and Application of Î -type Miniaturized Lumped Equalizer

Abstract

A novel lumped equalizer is presented in this paper. The equalizer is constructed with Π-type lumped network. The theory of the structure is analyzed and the derivation of element values is discussed with application. The simulation results are in agreement with theoretical deduction. The test results in transmitter application show that the gain fluctuation of ±2dB can be reduced to ±0.3dB in the working frequency 0.2-1GHz. The test results are in good agreement with the design values.
