All external circuitry parts are readily available, low cost surface mount components (.060 in. x .030 in. or .080 in. x .050 in.). 5. Pin 2 allows use of an external resistor to ground for optional, higher current. For I,, ~ 5 mA, R1 = 150 ohms; I,, ~ 6.5 mA, R1 = 120 ohms; I,, ~ 20 mA, R1 = 27 ohms. Cross Section View RF Traces + Components RF Ground DC Routing Customer Defined 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 is 1 ounce copper. |
