Precautions External capacitors should connected input output terminals (P1, block current. values these capacitors depend frequency range. Please 0.01uF capacitor 100MHz, 0.1uF capacitor 500MHz, 56pF capacitor 500MHz 2GHz. Decoupling capacitors should connected control terminals (VCTR1, VCTR2) close possible. values these capacitors should selected 0.01uF 100MHz, 0.1uF 500MHz, 10pF 500MHz 2GHz. Please take care select these values because capacitors make switching time long. order keep good isolation characteristics, ground terminals pin) should connected ground pattern with wider width close possible, through-hole ground plane should also placed close possible. isolation port port greater than isolation port port. Please consider this information create better isolation design.
