This document presents the frequency stability test results for LTE Band 5, as detailed in report PD20250070-R3A. The tests were conducted to ensure compliance with regulatory requirements for frequency stability under varying voltage and temperature conditions. The report includes comprehensive data for different bandwidths (1.4MHz, 3MHz, 5MHz, and 10MHz) and modulation schemes (QPSK).
The tests involved measuring the frequency deviation in Hertz (Hz) and parts per million (ppm) under different voltage levels (VN, VL, VH) and temperature ranges (-30°C to +50°C). The results are presented in tabular format, showing the RB configuration, voltage, temperature, frequency deviation, and verdict (PASS/FAIL) for each test case. The limit for frequency deviation is set at ±2.5 ppm.
The tests were performed using QPSK modulation. The results indicate that the device meets the frequency stability requirements for LTE Band 5 under all tested conditions. The document provides detailed information for regulatory compliance and performance evaluation of the device.
