For good RF performance, the ground terminals must be placed possibly close to ground plane of substrate, and through holes for GND should be placed near by the pin connection. Bypass capacitor (C4) should be placed close to terminal of VDD to reduce stripline influence of RF characteristics. -6- NJG1666MD7 PACKAGE OUTLINE (EQFN14-D7) Units Board Terminal treat Molding material Weight : mm : Cu : SnBi : Epoxy resin : 3.3mg 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.
