Huajinda Electronic (HJD) produces surface acoustic filters, resonators; abbreviated as SAW. The principle is to use the piezoelectric characteristics of piezoelectric crystal materials, use input and output transducers to convert the input signal of electric wave into mechanical energy, after processing, mechanical energy into electrical signal, and ultimately filter unnecessary signals and clutter to improve the efficiency of received signal. The main function is to filter out clutter, which is simpler and smaller than the traditional LC filter.
Surface acoustic filters are mainly divided into IF filters, RF filters and RF Resonators. SAF and resonator are widely used in wireless communication, multimedia, communication base station, mobile phone, TV, set-top box, network system, satellite positioning system, wireless remote controller, alarm. Huajinda mainly produces SAF for TV sets, set-top boxes, wireless remote control, alarms and cordless telephones, which occupies a favorable position in China. Secondly, SAF for communication products is the direction of our efforts. At present, we have established technical cooperation and product cooperation projects with leading enterprises in the same industry in Korea, which HJD can provide at present. Frequency can reach 2.64 GHZ, SMD surface paste size can reach 1.4*1.1 mm, the main (RF) SMD size is 5.0*5.0, 5.0*3.5, 3.8*3.8, 3.0*3.0, 2.5*2.0, 2.0*1.6, 2.0*1.4, 1.4*1, etc. to meet the future needs of the mainland market. For detailed product packaging, please refer to Huajinda's home page (http://www.gdqfk.com) for the model and consult if you have any questions (Email: email@example.com). Regardless of the size of the product and the cutting-edge performance indicators, we are dedicated to providing customers with quality-guaranteed products, superior prices and satisfactory delivery dates.
