Notes:
• Recommended PCB material is 10 mils Rogers RO4350.
• Suggested component values may vary according to layout and PCB
material.
• L1 and C1 form the input matching network.
• L4 and C7 form the output matching network.
• L2, L3, C5 form the inter-stage matching network.
• R2 and C4 form the network for externally gain adjustment feature.
(optional)
• R4 and C18 form the network for externally gain adjustment feature.
(optional)
• Cs, C6, C13 are RF bypass capacitor.
• C16 mitigates the effect of external noise pickup on the Vbias line.
• R1 is bias resistor for Q1.
