Typical Bias Configuration
Application notes related to biasing circuit, device footprint, and thermal considerations are available on request.

RF IN
Description
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 applica-
tions. 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:

Care should also be taken in the resistor selection to ensure that the cur-
rent 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.
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.
