When the other device is biased at certain voltage and connected to the NJG1681MD7, a DC block capacitor is required between the device and the switch IC. This is because the each RF port of NJG1681MD7 is biased at 0 V (GND). [2] For avoiding the degradation of RF performance, the bypass capacitor (C1) should be placed as close as possible to VDD terminal [3] For good RF performance, all GND terminals are must be connected to PCB ground plane of substrate, and through - holes for GND should be placed the IC near. -9- NJG1681MD7 I RECOMMENDED FOOTPRINT PATTERN (EQFN14-D7 PACKAGE Reference) :Land :Mask (Open area) *Metal mask thickness : 100µm :Resist(Open area) Detail A - 10 - PKG: 1.6mm x 1.6mm Pin pitch: 0.4mm NJG1681MD7 I PACKAGE OUTLINE (EQFN14-D7) Units Board Terminal treat Molding material Weight : mm : Cu : SnBi : Epoxy resin : 3.4mg Exposed PAD Ground connection is required.
