EFR(01)-240X240T0800

RFI and EMI shielding and absorbing materials are used to protect against electromagnetic interference (EMI) and radio frequency interference (RFI). EFR(01)-240X240T0800 is one such product, a ceramic substrate based on the advanced electrically-erasable programmable read-only memory (EEPROM) technology. In this article, we will discuss its application field and working principle.

EFR(01)-240X240T0800 is a good choice for applications involving high-frequency RF signals and low power communication. It is used in systems such as ultra high-definition television (UHDTV) broadcast reception, cellular telephones, RFID systems, satellite navigation and broadband communication. It is typically used in combination with EMI shielding and absorbing materials to protect sensitive electronic equipment from EMI/RFI interference by providing a shield against electromagnetic radiation.

EFR(01)-240X240T0800 consists of a patterned array of electrodes that can be programmed to reflect a signal and absorb another signal. It acts as a reflection phase shifter, using the reflection phase shift principle to reduce the amount of interference generated by radio frequency signals. The patterned electrodes are made of gold-plated copper, nickel, silver, or other metal that can be selectively etched and patterned. The electrodes are connected to a ceramic substrate which is used as a shield between the interfering signal and the sensitive electronic components.

The working principle of EFR(01)-240X240T0800 is based on the reflection phase shift principle. When radio frequency (RF) energy is incident on this device, a portion of the energy passes through and is reflected back to its source. The portion of the energy passing through the device is reduced in amplitude and phase while the portion reflected back is substantially increased in amplitude. This increase in amplitude of the reflected signal is due to the reflection phase shift generated by the patterned array of electrodes. The reflected signal is then blocked by the ceramic substrate, providing EMI/RFI shielding and absorption.

EFR(01)-240X240T0800 is used mainly in applications where EMI/RFI shielding and absorption are critical, such as satellite and terrestrial communication, broadcast reception, and wireless power detection. It is also used in the aerospace industry, automotive industry, medical applications, consumer electronics, and automotive navigation systems. In addition, it can be used as an EMI filter to reduce the amount of interference generated by devices such as computers, cell phones, and other telecommunication equipment.

In summary, EFR(01)-240X240T0800 is a high-performance ceramic-substrate based product used for RF EMI/RFI shielding and absorption applications. It utilizes the reflection phase shift principle to reduce the amount of interference generated by radio frequency signals. This product is used in many different industries, including aerospace, automotive, and consumer products.
