Abstract
A microwave power combiner/divider is matched internally and has increased bandwidth. A microwave integrated circuit disk within the housing has high impedance radially directed quarter-wavelength lines to obtain an impedance match for the desired mode at the centered coaxial port. Bridging half-wavelength lines between adjacent peripheral ports match the undesired mode and connect to absorbing resistors; these lines also provide bandwidth compensation. The housing has an annular shield with an opening near the centered coaxial line to provide a high choke impedance.
