High-density microwave amplifiers, widely used in radar, satellite communication, and 5G mmWave systems, operate under intense thermal stress and high RF power. Maintaining ultra-low insertion loss, precise phase stability, and tight impedance control is critical to ensure amplifier efficiency, signal fidelity, and overall system reliability. RO4835 PCB laminates (Dk = 3.48 ± 0.03, Df =...
