TERMINAL INFORMATION

SYMBOL
DESCRIPTIONS
1
P1
RF port. This port is connected with PC port by controlling 6
th
pin (V
CTL (H)
)
to 2.5~6.5V and 6
th
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
GND
Ground terminal. Please connect this terminal with ground plane as close
as possible for excellent RF performance.
3
P2
RF port. This port is connected with PC port by controlling 4
th
pin (V
CTL(H)
)
to 2.5~6.5V and 4
th
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)
4
VCTL2
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 (2.5~6.5V) or low-state (-0.2~+0.2V). The voltage of 6
th
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
VCTL1
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 4
th
pin have
to be set to opposite state. The bypass capacitor has to be chosen to
reduce switching time delay from 10pF~1000pF range.
