Demoboard and application schematic diagram series) will yield lower NF and higher Gain. higher gain can be obtained by increasing the value of C2 but at the expense of stability. mitigate the eff ect of external noise pickup on the Vdd and SD lines respectively. These components are not required in actual operation. The output of the module is internally ac-coupled to pin 8. Bias control is achieved by either varying the SD voltage with/ without R2, or fi xing the SD voltage to Vdd and adjusting R2 for the desired current. R2 = 3.9 kOhm will result in 6mA when Vdd=Vsd = 2.7V and 4mA when Vdd = Vsd = 1.8V.

In this regard, the Fmin of the ALM-1612 shown above is locked down by the internal input pre-match. This allows the use of relatively inexpensive chip inductors for external matching.
