Abstract
A series transmission line transformer is set forth which includes two or more of impedance matched sets of at least two transmissions lines such as shielded cables, connected in parallel at one end ans series at the other in a cascading fashion. The cables are wound about a magnetic core. The series transmission line transformer (STLT) which can provide for higher impedance ratios and bandwidths, which is scalable, and which is of simpler design and construction.
Claims7
A series transmission line transformer comprising:
- input and output connections having a desired impedance relationship;
- a first set of at least two coiled transmission lines electrically connected in parallel at one and in series at the other end;
- at least a second set of at least two coiled transmission lines connected in parallel on one end and in series on the other end, said first set of lines cascaded with the other sets, each impedance of a set matched to the next, said input and output connected to said first and last set of said cascade.
