The voltage of this port controls PC to P1 state. The `ON' and `OFF' state is toggled by controlling voltage of this terminal such as high-state (2.5~5.5V) or low-state (-0.2~+0.2V). The voltage of 3rd pin has to be set to opposite state. The bypass capacitor has to be chosen to reduce switching speed delay from 10pF~1000pF range. Common RF port. In order to block the DC bias voltage of internal circuit, an external capacitor is required. (1~500MHz: 1uF, 0.5~2.5GHz: 56pF) Control port 2. The voltage of this port controls PC to P1 state. The `ON' and `OFF' state is toggled by controlling voltage of this terminal such as high-state (2.5~5.5V) or low-state (-0.2~+0.2V). The voltage of 1st pin has to be set to opposite state. The bypass capacitor has to be chosen to reduce switching speed delay from 10pF~1000pF range. RF port.

Please use a 0.1uF capacitor at 1 to 500MHz, a 56pF at 500MHz to 2.0GHz. [2] To avoid coupling between terminals, the capacitors have to be placed at the control terminals (VCTR1 , VCTR2 ) as close as possible. The capacitor values of 1000pF at 1 to 500MHz, 10pF at 500MHz to 2GHz are desired. In general, the switching time is depending on the capacitor values, so please be careful choosing capacitor values. [3] For good isolation characteristics, the ground terminals (5pin) should be directly connected to the ground patterns and through-holes as close as possible using relatively wide patterns. -8- NJG1512HD3 n PACKAGE OUTLINE (USB10-D3) PKG MR K A-A cross section 45 0.8 0.038 0.018 A A 0.3 0.2 0.5 1.8 0.5 R0.075 0.8 1 2 0.3 Please connect with GND terminal.
