All external circuitry parts are readily available, low cost

surface mount components (.060 in. x .030 in. or .080 in.

x .050 in.)

10. Pin 2 allows use of an external resistor to ground for

optional, higher current.

For IDD ~ 5 mA, R1 = 150 ohms;

IDD ~ 6.5 mA, R1 = 120 ohms;

IDD ~ 20 mA, R1 = 27 ohms.

Cross Section View

The PCB dielectric between RF traces and RF ground layers

should be chosen to reduce RF discontinuities between 50 Ω lines

and package pins.

M/A-COM recommends an FR-4 dielectric

thickness of 0.008” (0.20 mm) yielding a 50 Ω line width of

0.015” (0.38 mm). The recommended RF metalization thickness is

1 ounce copper.
