Description
Ground connection. For best performance, keep traces physically
short and connect immediately to ground plane.
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 instability.
Ground connection. For best performance, keep traces physically
short and connect immediately to ground plane.
RF output and bias pin. Biasing is accomplished with an external
series resistor and choke inductor to V
CC
. The resistor is selected
to set the DC current into this pin to a desired level. The resistor
value is determined by the following equation:

GND
RFOUT
Care should also be taken in the resistor selection to ensure that
the current into the part never exceeds maximum datasheet
operating current over the planned operating temperature. This
means that a resistor between the supply and this pin is always
required, even if a supply near 5.0V is available, to provide DC
feedback to prevent thermal runaway. Alternatively, a constant
current supply circuit may be implemented. 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.
