Abstract
A MMIC (microwave monolithic integrated circuit) driver amplifier having a zig-zag RF signal flow and method for the same is provided. A smaller die size and higher output gain are realized with the improved amplification stage geometry provided herein. In particular, the stages are configured in a “stacked” topology permitting a zig-zag RF signal flow through the stages. Additionally, the DC bias circuitry may be is centralized and adjacent stages may share vias. The die area for a typical K-band driver amplifier may be reduced by about 56% over a conventional amplifier design.
