Abstract

An active filter structure is developed, fabricated, and demonstrated as a monolithic microwave integrated circuit (MMIC). This filter structure makes use of both lumped elements and active transversal elements. The filter uses lumped elements to achieve a basic bandpass filter response, and transversal elements to sharpen the bandpass characteristic. Active elements are included to overcome the high loss of MMIC lumped elements. This miniature MMIC filter has a passband of 9.8-11.1 GHz with 2-dB loss and better than 30-dB rejection 1.1 GHz from either passband edge.<>
