Abstract
A magnetostatic wave device for microwave signal processing which includes an input or output transducer finger arrangement which allows shaping of the device response. Two sets of interdigitated fingers are connected to receive the same microwave input signal which is power divided between the two sets. The fingers of one set are substantially parallel to, and in side-by-side relationship with, the fingers of the other set. The device may be used for delay lines, filters, signal correlation, oscillators and numerous other microwave signal processing arrangements.
Claims11
A magnetostatic wave device operable within a biasing magnetic field, comprising:
- (a) a magnetostatic wave supporting material;
- (b) first and second spaced apart microstrip coupling sections in operative relationship with said material;
- (c) each said section having at least one finger member in substantially parallel side-by-side relationship with the finger member of the other said section;
- (d) means for electrically connecting both said sections together so as to be electrically in parallel in a manner that if said device is operated as a launcher of magnetostatic waves by coupling to an input microwave signal the current in said side-by-side fingers will be in opposite directions and if said device is operated as a magnetostatic wave receiving currents will be induced in said side-by-side fingers, which currents are in opposite directions.
