The short distance RF communication technology has many standards,the components supporting these standards general have bigger power consumption,the structure is complex,the price is higher,do not suit the low end application.
A kind of short distance wireless data transmission chipset—RFW102 chipset is introduced,comparing with other short distance RF communication in high end product application,it has merit of simple interface,low cost,no sensitively to noise disturbance,low power consumption,and so on.
Because the IC card technology includes VLSI circuit technology、RFtechnology、MCU tecbnology and information security technology, it is difficult todesign and develop a high-performance、low-power contactless IC card。 Studentsare doing many researches about the card。
Using a fast vision system, we obtain the configuration of each robot, and then the host computer computes the desired motion and commands each robot directly via RF communication.
Si1-xGex material has many unique characteristics.The high performance strained epitaxial layer can introduce the concept of bandgap energy into the column devices.The epibase Si1-xGex heterojunction bipolar transistor (HBT) results in good performance.Because of the compatibility with Si process and the rapid progress of Bi CMOS integration,the Si1-xGex devices and process have already reach the industry application level.The development of Si1-xGex process and the improvement of the microwave circuits pr...

A MEM variable capacitor for RF communications systems was presented.The capacitor was designed using a novel two-gap structure,using aluminum as the capacitor electrode material,using “Y” shape beams as the suspend electrode spring,and using a asymmetry thickness plate as the suspend electrode.The C-V characteristic was simulated by CoventorWare software.The capacitance of the signal capacitor is variable from 0.37 pF to 5.64 pF as the control voltage is swept from 0 to 10V,and the capacitance ratio is 15....
