Introduction

RF receivers, transmitters, and transceiver finished units are commonly used in today\'s wireless technologies. This article describes the application field and working principle of the XM-C92-2P-UA, a unidirectional RF receiver and transmitter finished unit.

Application Field

The XM-C92-2P-UA unidirectional device is mainly used in wireless communication systems such as police radio, military communication systems, broadcast and TV, and aviation communication networks. It is widely applied for infrastructures, vehicle-mounted, and airborne products such as radios, mobile phones, base stations, repeaters, aircraft, helicopters, etc.The XM-C92-2P-UA is a High-Gain Low-Noise unidirectional RF receiver and transmitter finished unit, supports -118dBm low noise figure, integrated gain-control, and up to +20dBm output power. It has an extended frequency range of 790KHz to 2600MHz. It has excellent linearity performance, which makes it suitable for low-power, high-gain applications. The device also has a temperature compensation/track clock that can keep the frequency and phase linearity consistent to an ambient temperature range of -20°C to +85°C, so it is well suited for harsh environment uses.

Working Principle

The XM-C92-2P-UA unidirectional RF receiver and transmitter finished unit is composed of RF effective circuit, signal processing circuit, amplifier circuit, up-conversion circuit, down-conversion circuit, and power supply circuit module.The RF controller circuit includes gain-control, frequency selection, and other components, whose functions are to receive and amplify the signal. When the amplifier circuit amplifies the received signal, a filter function is also executed to reduce external signal interference. The mixer circuit is then used to mix the amplified original signal with an image signal and a local oscillation signal.The signal processing circuit is used to process the signal to achieve the required characteristics, allowing for the fine-tuning of signal strength and signal-to-noise ratio. It also filters the image signal and unwanted noise.The up-conversion circuit is used to convert the received signal from low frequency to high frequency. It uses local oscillation signals to mix and modulate the received signal.The down-conversion circuit is used to convert the signal from the high frequency to the low frequency. It uses local oscillation signals to mix and demodulate the signal.Finally, the power supply circuit provides DC power to the system and isolates it from the external power source.

Conclusion

In conclusion, the XM-C92-2P-UA unidirectional receiver and transmitter finished unit is a versatile and reliable device, widely applicable for a number of wireless communication systems. Its application field is broad, and its working principle is based on the conversion of low frequency signals to high frequency signals. The device also has a number of features, such as gain-control, image and noise filtration, and temperature compensation/tracking for harsh environment uses. The XM-C92-2P-UA is an excellent choice for users to integrate into their wireless application systems.
