 Miniature wide-band microwave power divider

Details
Inventors: Beckwith, William B.;
Assignee: Motorola, Inc. (Schaumburg, IL)
Primary Examiner: Gensler; Paul
Assistant Examiner:
Attorney, Agent or Firm: Powell; Jordan C.

A miniature wide-band microwave power divider comprising a common terminal connected to a plurality of parallel signal paths with each signal path comprising a low pass and a high pass filter made up of discrete components. Use of discrete components allows the entire power divider to be incorporated on a single chip. Isolation is achieved between the signal paths by isolation means comprising resistors.

DETAILED DESCRIPTION A wide-band microwave power divider/combiner is provided in accordance with this invention which can be miniaturized to fit on a single chip.
To increase the bandwidth while maintaining good isolation performance, the invention contemplates coupling low pass filters and high pass filters in series along a plurality of signal paths and connecting the signal paths with isolation resistors.
These filters comprise discrete components.
By using discrete components, the entire wide-band power divider can be incorporated on a single I.
C.
chip.
It is, therefore, an object of the present invention to provide a wide-band microwave power divider/combiner.
Another object of the present invention is to miniaturize the power divider/combiner.
A further object of the present invention is to allow the power divider/combiner to be constructed in I.
C.
form.
Other objects and advantages of the present invention will become apparent from the following detailed description, particularly when considered in conjunction with the accompanying drawings.
