Abstract :
Novel vertical integrated transformers using bondwires are proposed and fabricated for low-cost and high performance MMICs. The new bondwire transformers are characterized experimentally in a wide frequency range from 1 to 20 GHz. The new transformers show lower power loss due to small ohmic loss of the gold bondwires and wide bandwidth compared to those of the planar spiral transformer.
