Specifications (in Production) Note: 1. The number and size of ground via holes in a circuit board is critical for thermal RF grounding considerations. 2. We recommend that the ground via holes be placed on the bottom of all ground pins for better RF and therm al performance, as shown in the drawing at the left side.

3/3 www.asb.co.kr August 2011 plerowTM ALN0667WT Internally Matched LNA Module 1) The tantal or MLC (Multi Layer Ceramic) 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. The ca- pacitor should be placed as close as possible to Vs pin and be connected directly to the ground plane for the best electrical performance. 2) 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 inclu d- ed inside the ALN module. Therefore, C1 & C2 c apacitors 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 fr e- quency.
