3 / 3 page 3/3 www.asb.co.kr December 2007 plerowTM ALN2502AT Internally Matched LNA Module 1) The tantal capacitor is optional and for bypassing the AC noise introduced from the DC supply. The capacitance value may be determined by customer ’s DC supply status. 2) So-called DC blocking capacitors are always necessarily placed at the input and output port for allowing only the RF signal to pass and blocking the DC component in the signal. The DC blocking capacitors are included inside the LNA module. Therefore, C1 & C2 capacitors may not be necessary, but can be added just in case that the customer wants. The value of C1 & C2 is determined by considering the application frequency. Application Circuit Recommended Soldering Reflow Process Evaluation Board Layout + - ALN OUT IN C1 C2 Tantal Capacitor V DC 20~40 sec 260 C 200 C 150 C 60~180 sec Ramp-up (3˚C/sec) Ramp-down (6 C/sec) Size 25 x 25mm IN OUT +Vcc (for ALN-AT, BT, T Series – 10x10mm) |
