Channel configurable type radio astronomy radiometer based on MMIC microwave radio detection chip

Abstract

A channel configurable type radio astronomy radiometer based on an MMIC microwave radio detection chip is formed by sequential connection of a power divider, an analog filter, a microwave switch, a microwave amplifier, a step attenuator, a secondary power divider, a commercial spectrometer, a radio detector, a multi-channel acquisition card and a terminal computer, wherein a digital control card is further arranged on the terminal computer. According to the radiometer, gating and configuration of different observation band widths are achieved through the control of the microwave switch, gain is controlled by controlling a gain controllable type radio-frequency amplifier to ensure that the input power of the radio detection chip to be within a certain range, and the influence of temperature on equipment can be reduced based on the low-temperature-offset wide-dynamic-range radio detection chip to guarantee the stability of observation data; finally, analog-digital conversion is conducted through the NI9215 data acquisition card at a rate as high as 100 Ksps, and observation at any integral time can be realized after sampling.

AI Technical Summary

Benefits of technology

This technology uses Program Controller (PC) controlled steps or pulse width modulation techniques to make sure certain parts on your circuit operate correctly without being affected from other things around them. It also includes various filtering devices such as inductors and capacitors used together with microelectronics components to reduce electromagnetic noise. Overall, this technology allows for precise measurement over longer distances while reducing unwanted signals outside specific ranges.

Problems solved by technology

This patents discuss various technical means related to Radiology Imaging Systems such as Digital Radio Interval Anomalous Lens Reflectometry (DRAL), Active Electron Laser Interceptor Compass Configuration Switched Capacity Ground Amplifier (AMLC)/Integrated Circuit Charging System (ICCS)) Receiving Units (RXUs)). Different techniques may help reduce errors caused by noise sources like magnetic waves or electric currents. One technique involves selecting specific measurements over certain spectral ranges instead of broad ones, but there exist challenges associated with conventional analog systems due to instabilities during operation. Another approach uses multi-channel electronics called MOSFET receivers combined together to improve overall functionality without compromising any desired features.
