Ultra-wideband millimeter wave miniaturized up-down conversion module

Abstract

The invention discloses an ultra wide band millimeter wave miniaturized up-down frequency conversion module, which comprises a down-conversion channel, a local oscillator generation circuit and an up-conversion channel, and is characterized in that the local oscillator generation circuit comprises a crystal oscillator, a three-way power divider, a first phase-locked loop PLL1, a second phase-locked loop PLL2 and two two-way power dividers; a first LO1 local oscillation signal of the local oscillation generation circuit is transmitted to an LO1 port of the down-conversion channel through an LO1-1 interface, and a second LO1 local oscillation signal is transmitted to an LO1 port of the up-conversion channel through an LO1-2 interface; a first LO2 local oscillation signal of the local oscillation generation circuit is transmitted to an LO2 port of the down-conversion channel through an LO2-1 interface, and a second LO2 local oscillation signal is transmitted to an LO2 port of the up-conversion channel through an LO2-2 interface. The working frequency and the working bandwidth of the frequency conversion module can be greatly improved, integration, miniaturization and universalization of the frequency conversion module are achieved, and therefore circuit implementation and control are easier.

For example, 0.38-18GHz is generally divided into 0.38-2GHz, 2-6GHz, 6-12GHz, and 12-18GHz. 4 Due to the complex multi-channel switch filter bank involved, the module size is relatively large, so it can only be designed independently and modularly

The traditional design method is to select the local oscillator signal below 20GHz for multiple frequency mixing. This kind of frequency conversion module has the disadvantages of large size, difficult debugging and high cost

The technical complexity and development cost of 18-40GHz millimeter wave ultra-wideband frequency conversion have also become the biggest problem
