Conversion Technology

in wireless communication network, the digital frequency conversion technology is a core technology, with the development of digital wireless technology, wireless technology is more and more mature, the broadband wireless infrastructure requirements also gradually improve, but because of limited technical level, the current signal in the frequency conversion process, RF signal after many simulation conversion into intermediate frequency, and then in the intermediate frequency conversion to digital, then can carry on the digital frequency conversion, unable to meet the demands of network development, this article discussed the technology of digital frequency wireless communication network optimization based on.

Active Folding

Based on the techniques of dynamic current injection, common source node resonance, second-order linearity performance and the application of CMOS technology, a 1.8V power supply voltage active folding Gilbert-type zero intermediate frequency mixer has been designed by using Candense design system. The result of circuit stimulation shows, single sideband noise figure is 6.109dB when the mixer locates at 1MHz, 6.71dB at 100KHz, 10.631dB at 10KHz. Frequency conversion gain is 11.389dB and input third-order intermodulation point is 4.639dBm.

Constant Field

The results of works aimed at increasing the level of uniformity of measurements of the magnetic induction of a constant field – the basic value in the field of magnetic measurements. A set of equipment for reproducing a unit of magnetic induction of a constant field in the range of 1–25 mT was created and described. The inclusion of this complex in the State primary standard of units of magnetic induction, magnetic flux, magnetic moment and magnetic induction gradient GET 12-2011 will ensure the reproduction and direct transmission of the unit of permanent magnetic induction in the ranges of not only weak (10–3–1 mT), but medium (1–25 mT) and strong (0.025–1 T) magnetic fields. A quantum cesium magnetometer based on the resolved structure of cesium atoms was created to transmit the unit of magnetic induction to the region of medium fields. The procedure for calculating the frequency conversion coefficients to magnetic induction of the created quantum cesium magnetometer is described. The uncertainty budget for reproducing a unit of magnetic induction of a constant field using the created complex is estimated.
