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 thermal performance, as shown in the drawing at the left side. 1-stage Balanced Type C o u p l e r C o u p l e r C o u pl er C o u pl er C o u pl er Outline Drawing (Unit: mm) (Top View) (Bottom side View) (Right side View) ALUC1405B1 Solder Stencil Area Ø 0.4 plated thru holes to ground plane (Recommended Footprint)

3/3 www.asb.co.kr January 2010 plerowTM ALUC1405B1 Internally Matched Balanced LNA Module Including Coupler 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 ALUC 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 fr e- quency.
