PRECAUTIONS [1] The DC current at RF ports must be equal to zero, which can be achieved with DC blocking capacitors (C1, C2, and C3). (However, in case there is no possibility that DC current flows, the DC blocking capacitors are unnecessary, i.e. the RF signals are fed by SAW filters that block DC current by nature, etc.) [2] To reduce stripline influence on RF characteristics, please locate the bypass capacitor C4, C5, and C6 close to VDD and VCTL terminal. [3] For good isolation, the GND terminals must be connected to the PCB ground plane of substrate, and the through-holes connecting the backside ground plane should be placed near by the pin connection. - 10 - NJG1698K84 RECOMMENDED FOOTPRINT PATTERN (QFN10-84) PKG : 1.15mm x 1.55mm Pin pitch : 0.4mm : Land : Mask (Open area) *Metal mask thickness : 100m : Resist(Open area) - 11 - NJG1698K84 PACKAGE OUTLINE (QFN10-84) TOP VIEW Unit Terminal treat Terminal core Molding material Weight : mm : Au : Ni : Epoxy resin : 1.5mg SIDE VIEW BOTTOM VIEW Cautions on using this product This product contains Gallium-Arsenide (GaAs) which is a harmful material. * Do NOT eat or put into mouth. * Do NOT dispose in fire or break up this product. * Do NOT chemically make gas or powder with this product. * To waste this product, please obey the relating law of your country.
