Abstract
A multicomponent network may be added to a transmission line in a high-frequency circuit to transform a first impedance of a downstream circuit element to second impedance that better matches the impedance of an upstream circuit element. The multicomponent network may be added at a distance more than one-quarter wavelength from the downstream circuit element, and can tighten a frequency response of the impedance-transforming circuit to maintain low Q values and low VSWR values over a broad range of frequencies.
Claims20
A circuit for impedance matching comprising:
- at least one transmission line;
- and
- a multicomponent network comprising a plurality of passive circuit elements coupled to the at least one transmission line, wherein:
- the at least one transmission line separates the multicomponent network from a source;
- and
- an impedance value of the at least one transmission line oscillates between an inductive impedance and a capacitive impedance, as measured along a length of the at least one transmission line in the circuit for impedance matching.
