Murata has partnered with Rohde & Schwarz to develop a high-precision, high-reliability RF measurement setup that bridges the gap between the theoretical potential of the software and the practical application of the hardware.

Murata's PMIC digitizes and optimizes the voltage required by the RF circuit, supports broadband signals such as 5G, and helps curb excessive power consumption. Murata's DPD algorithm achieves further power consumption reduction by minimizing distortion and noise in the RF circuit. The DPD algorithm is most effective when incorporated into the product's BBIC/RFIC. The RF measurement system verifies the technology's capabilities on realistic hardware, enabling platform manufacturers' integrated circuit development teams to make informed decisions and collaborate effectively and quickly with Murata. This advanced solution integrates Murata's innovative hardware with the sophisticated capabilities of Digital ET from Eta Wireless Inc. (a Murata subsidiary since 2021).
The RF measurement system consists of Rohde & Schwarz's advanced 5G NR-compatible test instruments (the R&S SMW200A vector signal generator along with the R&S FSW signal and spectrum analyzer) and Murata's FPGA board with the implemented DPD algorithm, the PMIC/Tracker module that supplies voltage according to Digital ET technology, and the controlling software. The test instruments support various communication standards, test methods, frequency bands, and modulation. The FPGA board outputs control signals while calculating the DPD and controlling the PMIC's output voltage, thus achieving highly efficient transmission. This setup allows integrated circuit manufacturers to explore the impact of Digital ET and DPD in various applications, helping to drive system development.
