  • We report an enhanced broadband passive combiner structure using a dense slot-line antenna array in an oversized coaxial waveguide. A significant reduction in size has been achieved while maintaining a 6-18GHz bandwidth and capacity for 32 MMIC amplifiers. A broadband slotline to microstrip line transition is also developed and monolithically integrated with the slot-line antennas, to eliminate a troublesome bond-wire transition in earlier design and provide better compatibility with commercial… CONTINUE READING
