TERMINAL INFORMATION
No.
SYMBOL
EXPLANATION
1
VCTL1
Control port 1. 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.
2
PC
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)
3
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
(2.5~5.5V) 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.
4
P1
RF port. This port is connected with PC port by controlling 1st pin (V
CTL (H)
) to
2.5~5.5V and 3rd pin (V
CTL (L)
) to -0.2~+0.2V. An external capacitor is required
to block the DC bias voltage of internal circuit. (1~500MHz: 1uF, 0.5~2.5GHz:
56pF)
5
GND
Ground terminal. Please connect this terminal with ground plane as close as
possible for excellent RF performance.
6
P2
RF port. This port is connected with PC port by controlling 3rd pin (V
CTL (H)
) to
2.5~5.5V and 1st pin (V
CTL (L)
) to -0.2~+0.2V. An external capacitor is required
to block the DC bias voltage of internal circuit. (1~500MHz: 1uF, 0.5~2.5GHz:
56pF)
