When using the CXG1017N, the following external components should be used:
C1: This is used for signal line filtering 100pF is recommended.
C2: This is used for RF De-coupling and must be used in all applications. 100pF is recommended.
Rrf: This resistor is used to stabilize the dc operating point at high power levels. A value of 75kΩ is
recommended.
D1: 6.2V Zenor diodes may be incorporated at the Control lines, as indicated, in order to give improved
ESD performance if necessary.
