We present the design and implementation of an S-band compact planar integrated filter integrated in a multi-layer ceramic substrate. The center frequency of the 3.8 mm x 2.4 mm x 0.5 ".front end image reject filter is 2.4 GHz, suitable for use in a Bluetooth wireless LAN transceiver system. Measurement results shows 3 dB insertion loss and 22 dB return loss at the center frequency.

Abstract-We present the first comprehensive experimental characterization of bond wire interconnects at microwave frequencies which includes a repeatability study, modeling and optimization. Wire bond interconnects with two different bond types (ball-crescent and wedge), two different loop types (tight and loose) and two different lengths (15 and 25 mils), were fabricated and experimentally investigated. We report the performance and repeatability comparison of these configurations and develop an electromagnetic as well as a simple wide band lumped-element equivalent circuit model to 40 GHz. A novel ribbon bond interconnect topology has also been proposed and experimentally tested demonstrating 65% less reflection compared to the conventional bond wire or ribbon configuration.
