Feature: 1. The amplifier module uses a 1.6mm thick PCB double side board, which makes it sturdy and durable and has a long service life. 2. Large heat dissipation area allows this RF power amplifier module to run for a long time and is stable and reliable. 3. This module is easy to use, has good performance, and its small size makes it easy to carry and store. 4. The impedance as low as 50Ω helps the radio frequency power amplifier module achieve up to 12.1 times the magnification. 5. Exquisite workmanship and reasonable design make it a perfect replacement for old or damaged products.
