RF Microstrip
Z0= 50 ohm
Caution:
1. This page is RF module, so should paymore attention to PCB layout.The RF Z0 is 50ohm,the drawing should fit
RF rules and RF portion must be put into one shielding case.
2. The value of components which marked asterisk "*" maybe tuned in different product. These components are in
RF matching nets, their values are effected bythe PCB material parameter,tolerance of component,and so on.
3. The idiosyncracyand tolerance of passive components such as capacitors,inductances, has been appointed.
These components just can be substituted bywhich are more high precision.
4. There are manyDCfiltering capacitors in the schematic,please put themclose to the source pins.Putting some
ground vias near to the ground pin and in gorund panel is well for DCfiltering and EMI rejection also.
