RF receivers are the front end of various wireless communication systems, supplying a pre-processed signal, which is useful to further operation. The SI4762-A50-GM is one of the RF receivers developed to cope with the modern day wireless communications that require higher bandwidths. This paper will discuss the application field of SI4762-A50-GM and as well as its working principle.

The SI4762-A50-GM is a multiband analog FM receiver that allows data exchange between a host processor and devices used in Wireless MicroN sensing applications. This device allows instructions to be utilized to enable FM broadcasts in multiple frequency bands, allowing targeted hardware to be more flexible and simplified compared to single-band FM receivers. The SI4762-A50-GM is compatible with commonly used remote control protocols, such as the Siemens Infrared protocol (aka SIR). It has the ability to be integrated into a variety of embedded devices, including televisions, automotive audio systems, and wireless speakers, with the required commands sent within AT commands interface.

In terms of application fields, the SI4762-A50-GM is ideally suited for wireless sensing applications with single-chip solutions where flexibility and scalability are of utmost importance. It is also designed with low-power consumption to meet the requirements of mobile and remote sensing applications. It is commonly used in environments where reliable communication is essential, such as the medical and industrial fields, due to its ability to support multiple frequency bands, as well as its compatibility with standard Remote Control protocols.

The SI4762-A50-GM’s working principle revolves around the analytical signal processing. This analyzes signals from the antenna and convert them from Range Energy Transfer (RET) to digital data. This digital data is then encoded by the Digital Signal Processing (DSP) unit, with all the data encoded into digital commands. These commands are then evaluated by a Field-Programmable Gate Array (FPGA) which also activates any external circuits. The signals are then sent to the AT commands interface where a host processor can access the data.

The SI4762-A50-GM is an incredibly versatile RF receiver that is designed for use in modern wireless communications. It allows data exchange between a host processor and devices used in Wireless MicroN sensing applications, and is compatible with commonly used infrared protocols. It is commonly used in environments where reliable communication is essential, such as the medical and industrial fields due to its ability to support multiple frequency bands. The SI4762-A50-GM utilizes a combination of analytical signal processing and Digital Signal Processing to communicate data between the antenna and the Field-Programmable Gate Array, where the information is encoded into digital commands before finally being sent to the AT commands interface.
