[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. nAPPLICATION CIRCUIT 2: Single control signal operation by using a transistor. - 10 - NJG1506R nTEST CIRCUIT nRECOMMENDED PCB DESIGN (TOP VIEW) PCB SIZE=19.5x14.0mm PC PCB: FR-4, t=0.2mm CAPACITOR: size 1005 C1 u P1 STRIPLINE WIDTH=0.5mm C3 C2 NJG1506R C4, C5: 10pF 1 C4 V CTR1 C1~C3: 56pF P2 C5 V CTR2 u: Please short between Pin4 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 900MHz. 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. - 11 - NJG1506R 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.
