It depends on what kind of power amplifier sample is required. If customers are after a product that does not require customization, namely a factory sample, it will not take long. If customers require a pre-production sample that need customization, it may take a certain period. Asking for a pre-production sample is a good way to test our capability to produce products out of your specifications. Rest assured, we will test the sample before shipping to ensure it lives up to any claims or specifications.
