context: can be seen that when the PA 2nd harmonic rejection ratio is above 56 dB, the MSD would be dominated by other impairments. Figure 6.2.5.1-3 UL 2nd harmonic MSD improvement over improved PA 2nd harmonic rejection ratio Observation 3: When the PA 2nd harmonic rejection ratio is above 56 dB, the MSD would be dominated by other impairments. Figure 6.2.5.1-4 shows the MSD improvement over LNA IP2 performance. It can be seen that the MSD though improved with increasing LNA IP2, the improvement is quite limited even with LNA IP2 up to 30 dBm. Observation 4: MSD though improved with increasing LNA IP2, the improvement is quite limited even with LNA IP2 up to 30 dBm. Figure 6.2.5.1-4 UL 2nd harmonic MSD improvement over improved LNA IP2 Based on the above observations, we can conclude that without PCB and antenna isolations improvement, the MSD from other improved RF parameters alone cannot be reduced to below 18 dB. Observation 5: Without PCB and antenna isolations improvement, the UL 2nd
description: A Low Noise Amplifier (LNA) is a type of device used in telecommunications to amplify weak signals while minimizing noise and distortion. In the context of 3GPP TS 38.881, LNA refers to a component that plays a crucial role in improving the performance of radio frequency (RF) parameters, specifically in relation to the second harmonic rejection ratio and intermodulation product (IP2).
explanation: The classification of LNA as a Device is based on its function as a physical component used to enhance signal quality in telecommunications systems. The context highlights its role in improving RF performance metrics, such as IP2, which justifies its categorization as a device.
