This document presents the frequency stability test results for LTE Band 7, as per the requirements outlined in the PD20250070-R3A report. The tests were conducted across various modulation schemes (QPSK), bandwidths (5MHz, 15MHz, and 20MHz), and channel configurations to ensure compliance under different operating conditions.
The report details the frequency deviation observed under varying temperature conditions (-30°C to +50°C) and voltage levels (VN, VL, VH). The results are presented in tabular format, including the frequency deviation in Hertz (Hz) and parts per million (ppm), along with the corresponding frequency limits. The tests were performed on multiple channels, including 21100, 20850, 21350, 21375, 20825, 21400, and 21100, to ensure comprehensive coverage.
The data confirms that the device maintains frequency stability within the specified limits under all tested conditions, ensuring reliable performance and compliance with regulatory standards. The report includes detailed measurements and analysis, providing a clear assessment of the device's frequency stability performance in LTE Band 7.
