Mini-Circuits recommends a 4-layer PCB with a solid ground plane, and a via-stitched ground plane around the amplifier. The input and output traces should be kept short and 50-ohm matched. A decoupling capacitor (e.g., 100nF) should be placed close to the amplifier's power pins.
-
To achieve the specified gain flatness and noise figure, ensure that the input and output impedances are matched to 50 ohms, and the amplifier is operated within its recommended operating conditions (e.g., voltage, current, and temperature). Additionally, use high-quality components and follow good PCB design practices.

The maximum input power that the MAV-11SM+ can handle without damage is +10 dBm. Exceeding this limit may cause permanent damage to the amplifier.
-
Yes, the MAV-11SM+ can be used as a receiver amplifier. However, the amplifier's noise figure will impact the overall system noise figure, and the gain may need to be adjusted to optimize system performance. Additionally, the amplifier's input impedance may need to be matched to the antenna or preceding stage impedance.
-
The thermal resistance of the MAV-11SM+ package is approximately 25°C/W. High temperatures can affect the amplifier's performance, including gain, noise figure, and linearity. Ensure good heat sinking and airflow to maintain a temperature below 85°C for optimal performance.
