High frequency source development at Calabazas Creek Research

Calabazas Creek Research, Inc. (CCR) is funded to develop a wide variety of RF sources from 81 GHz to 2 THz. Two traveling wave tubes are in development at 83.5 GHz for satellite communications applications. Development was performed on an overmoded, suspended ladder circuit at 95 GHz for high power applications. Two sources are in development at 650 GHz. CCR is continuing development of a 600-700 GHz backward wave oscillator and is funded to develop a 650 GHz TWTA (including the power supply). This TWT design incorporates a sheet electron beam and a planar circuit. To address high peak power applications, CCR is developing a gyrotron to generate peak power pulses exceeding 5 kW from a few hundred GHz up to 2.0 THz.
