The proper values for the components are dependent upon the intended frequency of operation. 2. The following values are contained on the evaluation board to achieve optimal broadband performance: Ref. Desig. Value / Type Size L1 39 nH wirewound inductor 0603 C1, C2 56 pF chip capacitor 0603 C3 0.018 μF chip capacitor 0603 C4 Do Not Place R4 24 Ω 1% tolerance 0805 Recommended Bias Resistor Values Supply Voltage R1 value Size 5 V 24.4 ohms 0805 6 V 46.7 ohms 0805 8 V 91 ohms 1210 9 V 113 ohms 1210 10 V 136 ohms 2010 12 V 180 ohms 2010 The proper value for R1 is dependent upon the supply voltage and allows for bias stability over temperature. WJ recommends a minimum supply bias of +5 V. A 1% tolerance resistor is recommended.
