RF Transceiver ICs is widely used in applications of low power wireless communication. EFR32FG13P233F512GM48-B is one of the popular RF transceiver ICs in the market. In this article, it provides an overview of the application field and working principle of EFR32FG13P233F512GM48-B.

EFR32FG13P233F512GM48-B is especially designed as a small size, low power, and high performance Bluetooth system-on-chip (SoC) transceiver IC. It is applicable to a wide variety of applications, such as wearable devices, industrial wireless sensor networks, and automotive applications. This IC has been released for a while and has been well proved in many projects.

In terms of performance, EFR32FG13P233F512GM48-B provides a maximum output power of +4 dBm while consuming only 12.5 mA transmit current. It also has a fast startup time of 10 ms and a high receiver sensitivity of -98 dBm. Moreover, it supports Bluetooth Low Energy (BLE), Bluetooth Classic, and ZigBee protocols. It also includes a hardware crypto engine which provides very secure data protection.

As for the application fields, EFR32FG13P233F512GM48-B is usually used in small form factor devices, like wearables and IoT sensors. With its low power consumption and small size, it is perfect for applications that require long battery life and a high integration level. In addition, it can also be used for building up a wireless bridge for data transmitting among various remote sensors and devices.

EFR32FG13P233F512GM48-B works on the 2.4 GHz ISM band. The frequency of this IC can be tuned up to +/- 20 kHz precisely. Besides, it is also equipped with the on-chip power amplifier which allows a higher signal quality. It also has multiple built-in receiving filters that are optimal for interferences. These features ensure EFR32FG13P233F512GM48-B has a high selectivity and rejection on interferences, so that the user can operate it in high interference environment.

The working principle of EFR32FG13P233F512GM48-B is quite simple. When there is no signal sent to the IC, it remains in the sleep mode and consumes very low power. When it comes to sending out a signal, it will first fetch the data from the memory block and pass it to the transmitting block, then the transmitted signal will pass through the on-chip power amplifier to increase the output power before it is sent out through the antenna. For the receiving side, the received signal will be processed by the IC and the data will then be passed to the data-transmitting block.

In conclusion, EFR32FG13P233F512GM48-B is an excellent RF transceiver IC which is designed for low power and high performance communication applications. It can be used for building up a wireless bridge for data transmission, and it also supports Bluetooth Low Energy, Bluetooth Classic, and ZigBee protocols. With its low power consumption, high performance, and small size, it is the perfect choice for wearables and IoT sensors applications.
