This paper studies the Ka-band frequency conversion amplifier circuit design and its temperature compensation technology.The basic principles of up-conversion amplifier module are discussed,RF gain and detector voltage temperature compensation is implemented,and an overall design with good temperature stability,linearity,and gain stability is presented.The module is composed of the unit circuit of the amplification circuit,temperature compensation circuit,mixer circuit,filter circuit and power amplifier.Agilent ADS software is used to develop the overall circuit design of the modules.Meanwhile,a combination of field simulation software and measurement is adopted to establish the model of the millimeter-wave components of multi-chip interconnect bonding wire,which integrates the parasitic inductance of the bond wires into the up-conversion amplifier module circuit design,thus significantly increasing the frequency response of the bonding wire circuit interconnection.The multi-chip assembly process is adopted for the production of high-performance variable frequency amplifier module.Test results show that the Ka-band output power is greater than 30.6 dBm with the full temperature range of power fluctuation less than 0.8 dB and the instructions full temperature detector voltage fluctuation less than 0.2 V,which is consistent with simulation results.
