Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using 50-ohm transmission lines for input and output signals.
The choice of input and output termination resistors depends on the specific application and the impedance of the signal source and load. A general rule of thumb is to use 50-ohm resistors for most applications, but it's recommended to consult the datasheet and application notes for specific guidance.
The LMH6704MFX/NOPB is rated for operation from -40°C to 85°C, but it's recommended to derate the device for operation above 70°C to ensure reliable performance.
To reduce EMI, it's recommended to use a shielded enclosure, keep the amplifier away from other noise-sensitive components, and use filtering or shielding on the input and output signals. Additionally, following good PCB design practices, such as using a solid ground plane and minimizing trace lengths, can also help reduce EMI.
It's recommended to use a 10-uF ceramic capacitor in parallel with a 100-nF ceramic capacitor to decouple the power supply. This will help to reduce noise and ensure stable operation.
