!TERMINAL INFORMATION
No. SYMBOL DESCRIPTION
1 P2
RF port. This port is connected with PC port by controlling 2nd pin (VCTL (H))
to 2.5~6.5V and 4th pin (VCTL(L)) to -0.2~+0.2V. An external capacitor is
required to block the DC bias voltage of internal circuit. (0.1~0.5GHz:
1000pF, 0.5~3GHz: 56pF, 3~5GHz: 27pF)
2 VCTL2
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 4th pin has
to be set to opposite state. The bypass capacitor has to be chosen to
reduce switching time delay from 10pF~1000pF range.
3 PC
Common RF port. In order to block the DC bias voltage of internal circuit,
an external capacitor is required. (0.1~0.5GHz: 1000pF, 0.5~3GHz: 56pF,
3~5GHz: 27pF)
4 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 (2.5~6.5V) or low-state (-0.2~+0.2V). The voltage of 2nd pin has
to be set to opposite state. The bypass capacitor has to be chosen to
reduce switching time delay from 10pF~1000pF range.
5 P1
RF port. This port is connected with PC port by controlling 4th pin (VCTL(H))
to 2.5~6.5V and 2nd pin(VCTL(L)) to -0.2~+0.2V. An external capacitor is
required to block the DC bias voltage of internal circuit(0.1~0.5GHz:
1000pF, 0.5~3GHz: 56pF, 3~5GHz: 27pF)
6 GND
Ground terminal. Please connect this terminal with ground plane as close
as possible for excellent RF performance.
