ABSTRACT:
The invention is a magnetically tunable bandpass filter for use in the miwave regions, particularly for frequencies between 0.1-4 GHz. A magnetically tunable bandpass filter is a filter which will pass only certain frequencies from one conductor to a separate conductor depending upon the frequency band and the magnetic field applied across the filter. The tuning of the center frequency can be achieved at relatively fast electronic switch times. The center frequency is the frequency at which the most coupling exist due to the applied magnetic field. Two striplines are placed at 90.degree. relative to one another with one end of one stripline overlapping one end of the other with the overlapped ends connected to ground. A disc of ferromagnetic material is placed between the two striplines. By applying a dc magnetic field and by changing the angle of the magnetic field within the disc plane, microwave signals can either be transmitted or not from one stripline to the other at a given frequency depending upon the applied magnetic field applied and the angle of application.
