This paper presents filters integrated in ultra thin multilayer organic substrate using 3D stitched capacitor alleviating shunt parasitics and providing tunable capacitors. Insertion loss of less than 2.2 dB, return loss of greater than 15 dB at 2.4 GHz and attenuation of greater than 30 dB below 2.0 GHz and at 4.7 GHz were measured. The measured results showed good agreement with simulated results. This paper demonstrated 2.4 GHz bandpass filters with size of 2.2 mm × 3.0 mm × 0.2 mm (1.2 mm3) in ultra thin organic RXP substrate.
