Thin film resistor microwave noise generator |
摘要 |
The invention is a novel noise reference generator for use in amplitude comparison radiometric systems for the purpose of rapid precision control of the over-all gain of the radiometer receiver. The reference generator operates by cyclic modulation of the temperature of a unique planar thin film microresistor which may be disposed in a constant temperature environment. A strip transmission circuit provides a common path for the microresistor heater currrent and for the generated noise signals, along with means for separating these currents.
