A Reduced-size Power Divider Using the Coupled Line Equivalent to a Lumped Inductor

A new method of reducing the size of a power divider using quarter-wave length transmission lines is proposed. The method utilizes a combination of shorted coupled lines instead of lumped inductors and capacitors. The new hybrid is simply fabricated wi...

In many applications, such as balanced power amplifiers, mixers and antenna systems, power dividers/combiners are required. Power dividers using quarter-wave lines become prohibitively large at the lower frequencies and result in MMIC chips of larger size and higher cost. The lumped-element approach, which uses lumped inductors and capacitors, is...
