Rlevel and Rbias are intended to achieve the required output level and to optimize the frequency smearing performance.

Rlevel has to be adjusted to the required output level (approximately 2 kΩ at VS = −12 V).

Rbias has to be tuned for the best high frequency smearing performance (200 MHz burst).
