Pin 1 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 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 VCC. 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:
Interface Schematic
2 3
GND RF OUT
RF OUT
( V CC - V DEVICE ) R = -----------------------------------------I CC
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. 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. Same as pin 2.
