ABSTRACT:
A transmission line filter includes first and second substantially parallel transmission lines (20, 30), with alternate ends grounded and each transmission line (20, 30) coupled through a separate capacitor (50, 60) to electrical ground. A coupling capacitor (70) connects the first and second transmission lines (20, 30). A RF output (40) coupled to the second transmission line (30) outputs a filtered RF signal in response to a RF signal input to a RF input (10) on the first transmission line (20). MIC and MMIC applications using series capacitance to allow for line length to be reduced include versions of a band pass filter (FIGS. 5, 6), band stop filter (FIG. 7), and low pass filter (FIG. 9).
