Analysis of the performance of the free electron bolometer
Abstract
The free electron bolometer (FEB) can be employed as a rugged, environmentally stable mixer and detector at frequencies above 100 GHz. This record shows how circuitry, material parameters, and operating conditions affect FEB performance. In particular, calculations of the expected noise equivalent power and noise temperature of the device are presented for general bias and IF matching conditions.
