READ MOREIn communication systems, RF coaxial connectors are widely used in the connection of device ports and equipment, in various forms and different usages. During the use process, many friends will have questions about whether their use is correct and whether it will cause damage to the product. Today w
READ MOREBasic knowledge of RF and microwave: basic concepts and terminologyRF basics1. Power/level (dBm): the output capability of the amplifier, the general unit is w, mw, dBmNote: dBm is an absolute power level expressed in decibels with 1mw as the reference value. Conversion formula:Level (dBm)=10lgw5W →
READ MORERF BMA connectorIn many applications, screw-on RF connections can sometimes appear stretched and even unusable: for example, panels, daughter cards, or inserts with multiple RF connection points.In these cases, the spacing between the connectors must be set to be very small, so that the nut cannot b
READ MOREBecause the attenuation effect seriously affects the operation of the communication network, PIM has attracted more and more attention in the field of wireless communication. As long as signals above two frequencies encounter a non-linear electrical junction or similar material, intermodulation will
READ MOREWhat is impedance matching? Why do we need impedance matching?What is impedance?In a circuit with resistance, inductance, and capacitance, the obstacle to alternating current is called impedance. Impedance is often expressed as Z. Impedance is composed of resistance, inductive reactance and capaciti
