C-MG2470-00 RF/IF and RFID

RF Transceiver ICs are among the most commonly used components in today’s electronic systems. As integrated circuits, they provide a combination of radio frequency (RF) broadcast and signal reception capabilities in a single package. The C-MG2470-00 is a commercial RF transceiver IC from Freescale Semiconductor that has applications in a wide variety of applications. This article provides an overview of the C-MG2470-00’s application field and working principle.

The C-MG2470-00 is a single-chip 2.4GHz low-cost, low-power, RF transceiver IC that supports Bluetooth Low Energy (BLE) and frequency hopping spread spectrum in surface acoustic wave (SAW) filter-free platforms. It is ideal for applications such as medical and health care, industrial automation, consumer electronics, home automation, and more. The C-MG2470-00 enables applications that require good RF performance, low power consumption, and cost. It combines a receiver and transmitter on a single die, enabling a Radio-In-Package (RIP) design that is smaller, lighter, and more cost-effective than traditional multichip transceiver designs.

The C-MG2470-00 has a number of features that make it suitable for different types of applications. It contains an on-chip radio frequency synthesizer and channel decoder for interference mitigation, a built-in power amplifier for increased transmission range, and selectable output power levels to suit the requirements of the application. It also features a Bluetooth low energy stack and a low power Bluetooth low energy radio to enable easy integration into Bluetooth low energy applications. The transceiver has a maximum output power of up to 71 dBm, a sensitivity of -107 dBm, and a channel data rate of 1 Mbps. The integrated power amplifier supports an output power of up to 15 dBm.

The working principle of the C-MG2470-00 is based on the direct conversion receiver architecture. This architecture uses a single mixer to convert the incoming RF signal directly to baseband, simplifying the circuit and reducing the component count. It also reduces idle current, and in turn power consumption. The direct conversion receiver offers good performance in terms of receiver sensitivity and accuracy. The receiver section of the transceiver incorporates an analog-to-digital converter, a channel decoder, and a Bluetooth low energy stack. The signal is received by the receiver, decoded, and then sent to the Bluetooth low energy stack for further processing. The target output is then transmitted via the transmitter section of the transceiver. The transmitter section contains a digital-to-analog converter, a power amplifier, and a frequency synthesizer.

In conclusion, the C-MG2470-00 is a versatile RF transceiver IC from Freescale Semiconductor that offers a combination of receiver and transmitter performance for a wide range of applications. Its application field includes medical and health care, industrial automation, consumer electronics, home automation, and more. The transceiver’s working principle is based on the direct conversion receiver architecture, and it incorporates an analog-to-digital converter, a power amplifier, and a frequency synthesizer to complete the signal processing. With features such as a maximum output power of up to 71 dBm, a sensitivity of -107 dBm, and a channel data rate of 1 Mbps, the C-MG2470-00 is a dependable solution for deploying integrated RF systems.
