High power strip line RF Power combiner - 8 way
Reducing RF power losses associated with N-Way power combining at Ka band frequency (29-30GHz). 8Way power combiner is required in the realization of 250W Ka Band Amplifier where eight amplifiers each 40W output will be combined. The combiner should have high combining efficiency and all input ports and output port shall be matched to 50ohms impedance.
Realization of High-power Amplifier combining multiple low power stages. Combining losses shall be less than 1dB. Developed RF combiner shall have loads to absorb the imbalance power between the input ports.
