Microwave Transmission Devices Comprising Gyromagnetic Material Having Smoothly Varying Saturation Magnetization
US Patent:
4390853, Jun 28, 1983
Filed:
Aug 12, 1981
Appl. No.:
6/292202
Inventors:
Moni G. Mathew - Sunnyvale CA
Thomas J. Weisz - Sunnyvale CA
Thomas J. Weisz - Sunnyvale CA
Assignee:
TRW Inc. - Redondo Beach CA
International Classification:
H01P 1387
H01P 136
H01P 1218
H01P 136
H01P 1218
US Classification:
333 11
Abstract:
A multi-port microwave device, such as an isolator or circulator, for transmission of electromagnetic energy in TEM and higher order modes non-reciprocally between parts. The device exhibits low insertion loss, high return loss (low VSWR) and high isolation and is operable over a 100 percent or more bandwidth. The microwave device includes a composite ferrite body between a circuit conductor and a ground plane. The composite ferrite body includes ferrite material having a saturation magnetization gradient for providing different frequency characteristics over the frequency pass band of the device.
Microwave Transmission Device Having Gyromagnetic Materials Having Different Saturation Magnetizations
US Patent:
4496915, Jan 29, 1985
Filed:
Dec 29, 1983
Appl. No.:
6/566861
Inventors:
Moni G. Mathew - Sunnyvale CA
Thomas J. Weisz - Sunnyvale CA
Thomas J. Weisz - Sunnyvale CA
Assignee:

International Classification:
H01P 1387
US Classification:
333 11
Abstract:
A multi-port microwave device, such as an isolator or circulator, for transmission of electromagnetic energy in TEM mode non-reciprocally between ports. The device exhibits low insertion loss, high return loss (low VSWR) and high isolation and is operable over a 100 percent or more bandwidth. The microwave device includes a composite ferrite body between a circuit conductor and a ground plane. The composite ferrite body includes at least two different types of ferrite material where each one is selected to provide different frequency characteristics over the frequency pass band of the device.
