Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important 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 values of Rf and Rg depend on the desired gain and bandwidth of the amplifier. TI provides a gain calculation formula in the datasheet, and a more detailed explanation can be found in the application note 'LMH6601 High-Speed Amplifier' (SLVA372).
The maximum power dissipation of the LMH6601MG is 1.4W. To ensure it doesn't overheat, make sure to provide adequate heat sinking, such as a thermal pad or a heat sink, and keep the ambient temperature below 85°C. Also, ensure that the input and output signals are within the recommended voltage ranges to minimize power consumption.
Yes, the LMH6601MG can be used as a single-ended amplifier. To do so, connect the non-inverting input (VIN+) to the signal source, and tie the inverting input (VIN-) to a fixed voltage reference, such as a voltage divider or a voltage regulator output. This configuration is useful when a single-ended input signal is available.
To minimize EMI, use a shielded enclosure, keep the input and output signals away from the device's power pins, and use a common-mode choke or a ferrite bead on the input and output lines. Additionally, ensure that the PCB layout is designed to minimize radiation and coupling between signals.
