Design and Implementation of X-band Up/Down Conversion Module WANG Xiaoping （Shanghai Picowave Electronic Technology Co.，Ltd.， Shanghai 2018o2，China）

Abstract： Microwave transceiver systems are widely used in fields such as communication and radar. The up and down conversion module converts RFand IF signals，which has asignificant impact on system performance. The X-band is widely used in militaryapplications suchas radarand satelitedue to its anti-nterference and low loss characteristics，andisaresearchhotspot.Thepurposeof thisarticleis todesignand implementX-bandupanddown conversion modules as partof the display platform.The up conversion module converts the S-band intermediate frequency signal intoanX-band radio frequencysignal，whilethe downconversion moduleperforms theopposite function. By using AltiumDesigner software for schematic and layout drawing，a physical PCB with dimensions of 84 mm*69 mm was produced. Combining the hardware system to build a testing platform，after debugging，the circuit has achieved the predetermined upand down conversion function，meeting the design requirements and succesfully demonstrating the X-band transceiver function.

Keywords： X-band; Up and down conversion; variable frequency loss
