Notes:

4. Pins 1, 4, 5 and 8 must be RF and DC grounded as shown.

This pin must be bypassed with a 500-pF surface mount MLC

capacitor, mounted as close as possible to pin 7, and RF decoupled

with a chip inductor having a minimum value of 15 nH (as shown in

the Recommended PCB Configuration).

6. Pin 2 allows use of an external resistor to ground for optional, higher

current bias. For nominal current operation no resistor is used.

For optional 20-mA current operation, connect a 35- to 40-ohm

chip resistor (as shown in the Recommended PCB Configuration).
