[1]Please connect bypass capacitors to the supply terminals of the C-MOS inverter. [2]In order to stabilize input impedance of inverter, please pull down using 510KΩ resister from the input terminal of the C-MOS inverter to the ground plane. nAPPLICATION CIRCUIT 2: Single control signal operation by using a transistor. - 11 - NJG1507R nTEST CIRCUIT nRECOMMENDED PCB DESIGN (TOP VIEW) PCB SIZE=19.5x14.0mm PCB: FR-4, t=0.2mm PC CAPACITOR: size 1005 C1 STRIPLINE WIDTH=0.5mm u C1~C3: 56pF R1 P1 C3 C2 NJG1507R 1 P2 C4, C5: 10pF R1: 510KΩ u: Please short between Pin4 C4 V CTR1 C5 V CTR2 and ground plane directly as close as possible. Precautions [1]External capacitors should be connected to the input and output RF terminals (P1, P2, PC) to block the DC current. The above example is a circuit at 1.9GHz. Please select the capacitor value suitable for actual frequency from 10pF to 1000pF. [2]Decoupling capacitors should be connected to the control terminals (VCTR1, VCTR2) as close as possible. The values of these capacitors should be selected from 5pF to 100pF range. Please consider that these values are very effective to switching time (Larger capacitor gives longer switching time). [3]In order to keep good isolation characteristics, the ground terminals (3, 4, 6pin) should be connected to the ground pattern with wider width as close as possible, and through-hole in the ground plane should also be placed as close as possible. - 12 - NJG1507R nPACKAGE OUTLINE (VSP8) Lead material Lead surface finish Molding material UNIT Weight 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. : Copper : Solder plating : Epoxy resin : mm : 22mg [CAUTION] The specifications on this databook are only given for information , without any guarantee as regards either mistakes or omissions.
