95 GHz Extended Interaction Oscillator Model VKB2437 INTRODUCTION CPI Canada (CPI) has manufactured millimeter wave Extended Interaction Klystron (EIK) vacuum tubes since 1969. EIKs generate or amplify millimeter wave energy through interaction between a linear electron beam and resonant cavities similar to conventional klystrons. EIKs achieve useful performance by incorporating a slow wave biperiodic ladder circuit to extend the interaction between electron beam and cavities. This allows EIKs to operate up to 280 GHz to-date at power levels suitable for a variety of applications SCOPE This document details the performance specifications for the VKB2437** Extended Interaction Oscillator (EIOs). The VKB2437** is a 95.0 GHz CW EIO manufactured to Communications & Power Industries Canada Inc. commercial workmanship practices. This EIK is compatible with CPI CW power supply model VPW2838.
