Description
No internal connections. It is not necessary to ground this pin.
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.
No internal connections. It is not necessary to ground this pin.

No internal connections. It is not necessary to ground this pin.
RF output and bias pin. Biasing is accomplished with an external series
resistor and choke inductor to V
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 80mA over the planned operating temper-
ature. 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.
No internal connections. It is not necessary to ground this pin.

Ground connection. To ensure best performance, avoid placing ground vias
directly beneath the part.
