TERMINAL INFORMATION
No. SYMBOL EXPLANATION
1 P1
RF port. This port is connected with PC port by controlling 6th pin (V
CTL (H)
)
to 2.5~6.5V and 4th pin(V
CTL (L)
) to -0.2~+0.2V. An external capacitor is
required to block the DC bias voltage of internal circuit. (50~100MHz:
0.01uF, 0.1~0.5GHz: 1000pF, 0.5~2.5GHz: 56pF)
2 EXTCAP
External capacitor terminal. The isolation characteristics depends on the value of the capacitor which connected with GND. An external capacitor is required to block the DC bias voltage of internal circuit. (50MHz~1.7GHz: 10pF, 1.7~2.5GHz: 5pF)
3 P2
RF port. This port is connected with PC port by controlling 4th pin (V
CTL (H)
)
to 2.5 – 6.5V and 6th pin(V
CTL (L)
) to -0.2~+0.2V. In order to block the DC bias voltage of internal circuit, an external capacitor is required. (50~100MHz: 0.01uF, 0.1~0.5GHz: 1000pF, 0.5~2.5GHz: 56pF)
4 V
CTL2
Control port 2. The voltage of this port controls PC to P2 state. The ‘ON’ and ‘OFF’ state is toggled by controlling voltage of this terminal such as high-state (2.5~6.5V) or low-state (-0.2~+0.2V). The voltage of 6th pin have to be set to opposite state. The bypass capacitor has to be chosen to reduce switching time delay from 10pF~1000pF range.
5 PC
Common RF port. In order to block the DC bias voltage of internal circuit, an external capacitor is required. (50~100MHz: 0.01uF, 0.1~0.5GHz: 1000pF, 0.5~2.5GHz: 56pF)
6 V
CTL1
Control port 1. The voltage of this port controls PC to P2 state. The ‘ON’ and ‘OFF’ state is toggled by controlling voltage of this terminal such as high-state (2.5~6.5V) or low-state (-0.2~+0.2V). The voltage of 4th pin have to be set to opposite state. The bypass capacitor has to be chosen to reduce switching time delay from 10pF~1000pF range.

RECOMMENDED PCB DESIGN
PRECAUTIONS
[1]The DC blocking capacitors have to be placed at RF terminal of P1, P2 and PC. Please
choose appropriate capacitance values to the application frequency.
[2]To reduce stripline influence on RF characteristics, please locate bypass capacitors (C4, C5)
close to each terminal.
[3]For good isolation, the GND terminal (2nd pin) must be placed possibly close to ground plane
of substrate, and through holes for GND should be placed near by the pin connection.
