Function
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 applications. DC coupling of the input is not allowed, because this
will override the internal feedback loop and cause temperature instabil-
ity.
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance.

RF OUT
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. At room temperature, this pin
will bias itself to 3.7V as long as the current is held between 20mA and
65mA. Thus the resistor value is determined by the following equation:
V
----------------------------------------
=
Care should also be taken in the resistor selection to
ensure that the
current into the part never exceeds 65 mA 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 3.7V is available.
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.
