When using the CXG1028ATN, 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 100kΩ is
recommended.
Rctl: This resistor is used to reduce the current consumption or to give improved ESD performance.
