Feature:1. Wide Coverage: Comes with a wide working frequency of 65‑110MHz, the power amplifier ensures stable signal reception.2. Reliable Work: The 0.1‑1mW input power is exactly the output power of a s9018 oscillator, meanwhile the output is 7‑8W.3. Working Hints: The high frequency FM power amplifier module must be connected to the nominal load before powering on.4. Ideal Antenna: Connect a antenna that resonates at the working frequency, and the standing wave should not exceed 1.5.5. Easy to Install: Designed to have a light weight and a compact size as well, the installation is very easy to finish.Specification:Item Type: Power Amplifier BoardMaterial: PCBOperating Frequency: 65-110MHzOutput Power: 7-8WInput Power: 0.1-1mWInput and Output Impedance: 50 ohmsInput and Output Terminal: SMA-K Female HeadWorking Voltage: 12V, 15V maximum.
