US Patent:

48251771, Apr 25, 1989

Filed:

Oct 16, 1987

Appl. No.:

7/109101

Inventors:

Randy Teague - Syosset NY
Michael E. Weinstein - Huntington Station NY

Assignee:

General Instrument Corporation - New York NY

International Classification:

H03F 368

US Classification:

330295

Abstract:

A broad band, balanced microwave component, such as an amplifier, includes an input Lange coupler having a first center frequency and an output Lange coupler having a second center frequency. The center frequencies of the two Lange couplers are offset or the coupling is different so that at least one of the cross-over points of the input Lange coupler is offset in frequency from both the cross-over points of the output Lange coupler. The pair of Lange couplers so offset in frequency yields no more than one peak in gain which is readily equalized by single-ended amplifiers within the balanced amplifier.

General Instrument Corporation - New York NY

International Classification:

H01Q 1312

US Classification:

343770

Abstract:

A probe-fed slot antenna is provided having an inner conductor, a cylindrical outer conductor coaxial with the inner conductor, and a plurality of slots in the outer conductor. A plurality of probes extend from the cylindrical outer conductor into the interior, each probe adjacent to one of the slots. A coupling ring is mounted coaxially between the outer and inner conductors to allow efficient transfer of RF energy to and from the slots.
