Introduction of SD344EVK

The SD344EVK evaluation and demonstration board is an engineering platform for system engineers to evaluate and demonstrate the features of the 3GPP LTE Category 4 Type 1 modem chip, MDM344. It provides engineers with all the necessary signals for the development of cellular communication systems.

Application Field

The SD344EVK can be used in a variety of applications, ranging from pre-study to design, development and testing of a 3GPP LTE Category 4 modem. It can enable developers to quickly study the modem features, transmit/receive signals, and develop their own test scenarios. It can also be used to evaluate the performance of the MDM344 modem chip.

Working Principle

The SD344EVK board consists of the MDM344 modem chip, peripheral interface module, RF daughter card, and a dedicated power module. The peripheral interface module contains interfaces such as USB, JTAG, and UART, interfacing the board to the host system. The RF daughter card consists of 5 interfaces, namely a GPS receiver, an Antenna primary power amplifier, PA/DAC power amplifier, TX module, and RX module. These interfaces can be used to receive and transmit data packets to the modem.The power module provides the required power supply for the board and can also be used to monitor the board temperature. The board is run by two separate power supplies (internal and external) to ensure a controlled operation.The operation of the SD344EVK is based on the Lab Tool which provides a graphical user interface (GUI) for evaluation and testing. The Lab Tool enables setting parameters related to power amplifiers, RF parameters, and baseband parameters and verifying modem performance. It also allows performing live transition and debugging test scenarios.

Conclusion

The SD344EKV is a comprehensive evaluation and demonstration board for 3GPP LTE Category 4 modem. It consists of the MDM344 modem chip, peripheral interface module, RF daughter card, and a dedicated power module. It provides the necessary interfaces to evaluate the performance of the modem and study its features. The Lab Tool provides an easy to use graphical user interface along with live transmission and debugging features. The SD344EVK is a great way to get started with the 3GPP LTE Category 4 modem development.
