Introduction

RF transceiver modules use the same circuit to transmit and receive a signal in radio frequency. The HL7688_1103055 is an example of an RF transceiver module that has both a receiver and a transmitter in a single unit. This document will explain the application field and working principle of the HL7688_1103055.

Application Field

The HL7688_1103055 is a multi-purpose module that is suitable for many different applications. It is commonly used in automotive security applications such as car keyless entry systems. It’s also used in industrial automation, as well as in household applications for remote controls. The HL7688_1103055 provides a reliable connection between the keyless entry system and the car by sending and receiving bidirectional signals. Another application of the HL7688_1103055 is in medical monitoring systems that use RF commuincation to collect data from remote patients. The module can be used to transmit weak signals from medical sensing equipment and implantables, and can also receive signals to process and display data. The HL7688_1103055 is able to support high data rates in multi-point configurations, which makes it well suited for medical monitoring applications.

Working Principle

The HL7688_1103055 uses a single integrated circuit to both transmit and receive signals in radio frequency. The module features both transmit and receive antennas, and utilizes an RF signal chain which works as follows: The transmit antenna sends out the data while the receive antenna receives the data. The data is first modulated onto a high frequency carrier at the transmitter, and then sent to the receiver. At the receiver, the data is demodulated and output as digital data.The HL7688_1103055 features low-power and low-noise characteristics that make it ideal for long range applications. It operates at a frequency range of 903-927 MHz, and supports communication data rates up to 250kbps. The maximum output power is +14 dBm, and its antenna gain is 5 dB.

Conclusion

The HL7688_1103055 RF transceiver module is a multi-purpose device that can be used for applications in automotive security, industrial automation, and medical monitoring systems. It is able to both transmit and receive signals in radio frequency, and utilizes an RF signal chain from the transmit antenna to the receive antenna. The module features low-power and low-noise characteristics, and is able to support data rates of up to 250kbps.
