Micromachined Bandpass Filter with a New Controlled Resonance in the Stopband for WLAN 5200 Filter Applications

The paper describes a new lumped filter design for WLAN 5200 applications. The filter is suspended on 6.4 mum dielectric membrane with a dielectric constant of 5 in order to decrease the losses in the inductors. The new proposed topology improves the attenuation characteristic by an additional inductor's implementation that controls a new resonance frequency in the stopband
