7. All external circuitry parts are readily available, low cost
surface mount components (.060 in. x .030 in. or .080 in.
x .050 in.)
8. Pin 5 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.
The PCB dielectric between RF traces and RF ground layers
should be chosen to reduce RF discontinuities between 50 Ohm
lines and package pins. M/A-COM recommends an FR-4 di-
electric thickness of 0.008” (0.20 mm) yielding a 50 Ohm line
width of 0.015” (0.38 mm). The recommended RF metalization
thickness is 1 ounce copper.
