Description
This presentation covers the CCN extension phase of the 94 GHz power amplifier project. In the original part of the project, over 400 mW of output power has been demonstrated on-wafer from a single GaN power amplifier MMIC. The packaged single chip module has demonstrated 25 dBm output power. Furthermore a 4-chip waveguide module package with integrated power splitter and combiner has been realized, but unfortunately with unexpected high loss and poor performance. The extension phase has focused on increasing the output power by using the newest GaN MMIC processing technology and a new 4-chip waveguide power combining module design. The new module has a measured output power of 28 dBm, at 9 dB large signal gain (about 3 dB gain compression). With respect to the large signal gain this is a 6 dB improvement over the old module.
