Abstract:
This talk will describe recent developments in broadband fixed-tuned receivers and sources at millimeter and submillimeter wavelengths. These components rely on a strong fusion between novel integrated planar diode technology and innovative broadband circuit topologies. Using these methods excellent performance can be achieved over full-waveguide bands without the need for mechanical tuners or electrical bias. Broadband multipliers have been developed over bands ranging from WR-12 (60-90 GHz) to WR-1.2 (600-900 Gliz). As an example, a WR-3.4 tripler (220-330 GHz), pictured below, yields efficiencies of 2-4% over the band. WR-3.4 triplers optimized for different input power levels have been developed, with output powers ranging from 1/4 mW to 1/2 mW for input powers from 15 mW to 50 mW. Broadband quintupler designs with efficiencies ranging from 0.2-0.6% have been developed. For example, a quintupler to 900 GHz has produced 66 uW of output power using 20 mW of input power. A quintupler to 1.6 THz is currently under development.
