APPLICATION CIRCUIT 1: Single control signal operation by using C-MOS inverter.
[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.

RECOMMENDED PCB DESIGN
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.
