EM2420-RTR RF Transceiver ICs is an advanced transceiver integrating RF and baseband blocks, a local oscillator, and an antenna switch. It is designed for short range, low power and low data rate transmission applications. By implementing modern radio techniques and the latest advancements in integrated circuit technology, it provides low power consumption, excellent receiver sensitivity, and high performance.

The EM2420-RTR is a complete radio transceiver for wireless networks, including short-range and low-data rate radio applications. It is a highly integrated wireless radio transceiver radio IC optimized for wireless mesh or point-to-multipoint applications where battery powered nodes need the performance, range, and power efficiency of a standard IEEE 802.15.4 Compliant transceiver IC. The transceiver is designed to provide reliable reception for long range and low power data communications. For short range wireless communications, the IC supports non-standard data rates with enhanced signal quality.

The EM2420-RTR supports an unmodulated packet radio communication scheme based on the IEEE 802.15.4 protocol. Both a transmitter and receiver are incorporated into the chip. The transmitter includes an up-converter with integrated filter, a power amplifier, and RF-components. The receiver includes a low noise amplifier, mixer, down-converter, RF-band pass filter, and baseband processor. The receiver baseband processor demodulates packets for further processing.

The EM2420-RTR also includes a local oscillator (LO) for signal reception and communication. By accurately controlling the LO, a number of data rate modes can be supported on the EM2420-RTR. The LO components include an oscillator, a voltage-controlled oscillator (VCO), and a phase-locked loop (PLL) system. These components are used to generate a stable carrier frequency for the transceiver.

The antenna switch, incorporated into the chip, allows the transceiver to operate at different frequencies for different applications. The antenna switch allows the user to select the antenna for the optimal performance depending on the application. The selection is based on the application and the size of the antenna. Additionally, the antenna switch can be used as a part of the receiver sensitivity adjustment.

The EM2420-RTR radio transceiver IC offers excellent performance and a low power consumption. It is well-suited for applications where low power or long-range communications is desired. It has been used successfully in various wireless applications including smart metering, building automation, motion detection, and home automation.

In summary, the EM2420-RTR radio transceiver IC is an advanced transceiver equipped with an antenna switch, an up-converter, a power amplifier, a low noise amplifier, a mixer, a down-converter, an RF-band pass filter, as well as a baseband processor and a local oscillator. The IC offers low power consumption, excellent receiver sensitivity and reliable high performance. Thus, it provides a great option for various wireless applications, such as smart metering, building automation, motion detection, and home automation.
