External Circuitry Parts List 8 Part Value Purpose C1 47 pF DC Block C2 470 pF By-Pass L1 2.7 nH Tuning L2 22 nH RF Choke R1 See note 9 Optional current control C3 470 pF By-Pass 8. All external circuitry parts are readily available, low cost surface mount components (.060 in. x .030 in. or .080 in. x .050 in.) 9. Pin 5 allows use of an external resistor to ground for optional, higher current. For IDD ~ 5 mA, R1 = 150 Ω; IDD ~ 6.5 mA, R1 = 120 Ω; IDD ~ 20 mA, R1 = 27 Ω. Functional Schematic Frequency 1700 MHz 1850 MHz 2000 MHz Γin (mag) 0.699 0.674 0.649 Γin (ang) 48.47° 38.68° 29.27° Input Reflection Coefficient Cross Section View 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.
