Pin  
1
Function Description  
Interface Schematic  
Ground connection. Keep traces physically short and connect immedi-  
GND  
ately to ground plane for best performance.  
Same as pin 1.

GND  
RF IN  
RF input pin. This pin is NOT internally DC blocked. A DC blocking  
capacitor, suitable for the frequency of operation, should be used in  
most applications. DC coupling of the input is not allowed, because this  
will override the internal feedback loop and cause temperature instabil-  
ity.  
Same as pin 1.

GND  
RF OUT  
RF output and bias pin. Biasing is accomplished with an external series  
resistor and choke inductor to V . The resistor is selected to set the  
RF OUT  
CC  
DC current into this pin to a desired level. The resistor value is deter-  
mined by the following equation:

Care should also be taken in the resistor selection to ensure that the  
current into the part never exceeds 75mA over the planned oper-  
ating temperature. This means that a resistor between the supply and  
this pin is always required, even if a supply near 3.6V is available, to  
provide DC feedback to prevent thermal runaway. Because DC is  
present on this pin, a DC blocking capacitor, suitable for the frequency  
of operation, should be used in most applications. The supply side of  
the bias network should also be well bypassed.
