[1]Please connect bypass capacitors to the supply terminal 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. n APPLICATION CIRCUIT 2: Single control signal operation by using a transistor. - 11 - NJG1509F n TEST CIRCUIT VCTR2 (2.7V/0V) 4 C2 P2 Zo=50Ω 3 C4 Zo=50Ω 5 Zo=50Ω 2 R1 PC C3 P1 C1 6 1 C5 VCTR1 (0V/2.7V) NJG1509F n RECOMMENDED PCB DESIGN (TOP VIEW) PC VCTR2 C3 C4 P2 C2 C1 R1 C5 P1 VCTR1 PCB SIZE=19.4x14.0mm PCB: FR-4, t=0.5mm CAPACITOR: size 1005 STRIP LINE WIDTH=1mm C1~C3: 56pF C4, C5: 10pF R1: 510KΩ Precaution [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 900MHz. Please select the capacitors 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 grand terminal (5pin) should be connected to the ground pattern with wide width as close as possible, and though-hole in the ground plane should also be placed as close as possible. - 12 - NJG1509F nPACKAGE OUTLINE (MTP6) Lead material Lead surface finish Molding material UNIT Weight : Copper : Solder plating : Epoxy resin : mm : 14mg 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.
