SHEET: 5/6
SAW-1.4*1.1mm
Digital IF Frequency:
4.092MHz
TCXO
RF Microstrip
Z0= 50 ohm
Caution:
1. This page is RF module, so should pay more 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 "*" may be tuned in different product. These components are in
RF matching nets, their values are effected by the PCB material parameter,tolerance of component,and so on.
3. The idiosyncracy and tolerance of passive components such as capacitors,inductances, has been appointed.
These components just can be substituted by which are more high precision.
4. There are many DC filtering capacitors in the schematic, please put them close to the source pins.Putting some
ground vias near to the ground pin and in gorund panel is well for DC filtering and EMI rejection also.
