With the opening of 5g era, network base stations and user equipment (such as mobile phones) become more and more slim and compact, and the energy consumption is also becoming lower and lower.
High frequency PCB refers to the special PCB with high electromagnetic frequency, which is used in the fields of high frequency (frequency greater than 300MHz or wavelength less than 1m) and microwave (frequency greater than 3GHz or wavelength less than 0.1M).
RF PCB(radio frequency PCB) is widely used in many fields, such as television, radio, mobile phone, radar, automatic identification system, etc. The term RFID (radio frequency identification) refers to the application of radio frequency identification signal to identify the target.
What is RF circuit board?RF pcbs are printed circuit boards dedicated to radio frequency (RF) circuits.
In a wireless communication system, only a small part of the front-end circuit works in the RF stage, which is commonly known as RF front-end circuit. The rest of the circuit is for low-frequency baseband analog and digital signal processing
Power line is an important way for EMI in and out of the circuit. Through the power line, the external interference can be transmitted into the internal circuit and affect the RF circuit index.
1. RF circuit layout principle,In the design of RF PCB layout, the following general principles must be given priority to:
If the analog circuit (RF circuit) and digital circuit work separately, they may work well. However, once they are put on the same board and work together with the same power supply, the whole system is likely to be unstable.
PCB high-frequency PCB refers to the special circuit board with high electromagnetic frequency, which is used in the fields of high frequency (frequency greater than 300MHz or wavelength less than 1m) and microwave (frequency greater than 3GHz or wavelength less than 0.1M).
Although good schematics do not guarantee good wiring, good wiring begins with good schematics. When drawing the schematic diagram, it is necessary to consider the signal flow direction of the whole circuit.
