Notice

Below information is subject to change

as conditions of the substrate.

1. Pin 16 & 20 is used for Vce of the inner bias

circuit. To eliminate bias line resonance you

need above 10mm transmission line and

adjust the position of C2, C3, C4 ,C5 and C6.

Also you can adjust spectrum regrowth about

bandwidth of signals which you want.

2. C10 : We recommend High-Q capacitor for

better output power performance. In this

document we used ‘4.3pF(251R14S4R3BV4,

EIA 0603) of Johanson Technology.

3.C7 : Non-critical 0 Ω.
