Description

1nH, (0402) 0.2pF, (0402) 22pF, (0402) 1pF, (0402) Vendor DARFON DARFON DARFON DARFON Tolerance ±0.3nF ±0.05pF ±5% ±0.05pF For these suggested values for the matching and tuning of com- ponents, the average frequency will be around 2442Mhz for the lower Band and around 5550MHz for the higher on a standard 80 x 40mm2 Evaluation board. Please note, these are average reference values which may need to be changed when different circuit boards or manufactures are used. 6 (Fine Tuning) 0.2pF, (0402) DARFON ±0.05pF
