These components are not required in actual operation. Bias control is achieved by either varying the Vsd voltage with/ without R2, or fi xing the Vsd voltage to Vdd and adjusting R2 for the desired current.

In this regard, the Fmin of the ALM-1712 shown above is locked down by the internal input pre-match. This allows the use of relatively inexpensive chip inductors for external matching.
