RF devices are high-frequency device modules that can be used in mobile communication terminals, automobiles, factory automation equipment, etc. There are many types, including RFID-related components such as RFID transceivers, RFID transformers, reader modules, etc. In addition, there are RF semiconductor-related components such as RF amplifiers, RF two-way radios, attenuators, etc. and RF device-related components such as dielectric resonators, etc. Care must be taken when choosing, as they are all very similar in shape. In addition, it is important to select the RF device according to the environment because there are some components that you must check the frequency, operating supply voltage, and operating temperature. When attaching an RF device, it is necessary to cut, mold, etc. the leads depending on the situation.
