The maximum operating temperature range for the MRF8S18120HR3 is -40°C to 125°C.
To optimize the layout, keep the RF traces as short as possible, use a solid ground plane, and avoid crossing RF traces with other signals. Also, use a common mode choke or ferrite bead to filter out noise and EMI.
The recommended PCB material is FR4 or Rogers 4350B, and the recommended thickness is 0.8 mm to 1.6 mm.
Tuning the MRF8S18120HR3 involves adjusting the input and output matching networks to achieve the best possible impedance match. This can be done using a network analyzer and a tuning software such as Genesys or ADS.
The maximum power handling capability of the MRF8S18120HR3 is 20 W, but it's recommended to derate the power handling to 15 W to ensure reliable operation.
