Material & Mechanical Characteristics Material of Radiator ceramic red Cable Type / Connector Type / Dimension / C. Environmental Operation Temperature - 20 ̊C ~ + 60 ̊C Storage Temperature - 30 ̊C ~ + 70 ̊C Shenzhen Xinhengyang Technology Co., LTD R & D, production and sales of professional wireless terminal antenna 二、Electrical Specification Those specifications were specially defined for Bainuo-Visual doorbell model. 三、VSWR 1 Measuring Method 1.A 50Ωcoaxial cable is connected to the antenna. Then this cable is connected to a network analyzer to measure the VSWR 2.Keeping this jig away from metal at least 20cm 2 Measurement frequency points and VSWR value 四、 Anechoic chamber Shenzhen Xinhengyang Technology Co., LTD R & D, production and sales of professional wireless terminal antenna Introduction: Microwave darkroom and no reflection chamber, absorbing short wave darkroom dark room. Microwave darkroom by electromagnetic shielding room, filtering and isolation, grounding device, the ventilation duct, indoor distribution system, monitoring system, ceiling wave material part. It is based on the wave absorbing material as the lining of the shield room, it can absorb the most of the electromagnetic energy into the six wall is a better simulation of the free space conditions. The main working principle of microwave anechoic chamber is according to the electromagnetic wave in the medium from the low magnetic guide magnetic direction of propagation rules, absorbing materials to guide the electromagnetic wave using high permeability, through resonance, a substantial absorption of electromagnetic wave radiation energy, by coupling the electromagnetic energy into heat energy. main performance ： Frequency range:400MHz ~ 6GHz ceiling reflected wave loss materials: 400MHz ~ 6GHz is equal to or more than 15dB (microwave absorbing material by composite wave absorbing materials, namely t…
