Abstract :
The first monolithic grid amplifier using a cascade differential-pair amplifier unit cell has been designed and measured. The grid is packaged using reflection architecture with waveguide input and output. The measured gain at 82 GHz is 5.5 dB. The measured output power is 110 mW with 2.5 dB residual gain. The size of the amplifier module is 20 mm×10 mm×10 mm.
