For best performance, keep traces physically short and connect immediately to ground plane. Same as pin 1. Same as pin 1. 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. Same as pin 1. Same as pin 1. Same as pin 1. 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:  V CC – V DEVICE  R = ------------------------------------------I CC 9 GND RF OUT RF IN 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. Same as pin 1.

DS130418 NBB-402 Application Notes Die Attach The die attach process mechanically attaches the die to the circuit substrate. In addition, it electrically connects the ground to the trace on which the chip is mounted, and establishes the thermal path by which heat can leave the chip. Wire Bonding Electrical connections to the chip are made through wire bonds. Either wedge or ball bonding methods are acceptable practices for wire bonding. Assembly Procedure Epoxy or eutectic die attach are both acceptable attachment methods. Top and bottom metallization are gold. Conductive silver-filled epoxies are recommended. This procedure involves the use of epoxy to form a joint between the backside gold of the chip and the metallized area of the substrate. A 150°C cure for 1 hour is necessary. Recommended epoxy is Ablebond 841LMI from Ablestik. Bonding Temperature (Wedge or Ball) It is recommended that the heater block temperature be set to 160°C ± 10°C.
