Port Functions
| Port | Function | Description | DC Equivalent Circuit |
|---|---|---|---|
| GND | Ground | DC and RF ground is provided through the backside of the die. The die should be connected to a DC/RF ground with high thermal and electrical conductivity. | - |
| I1 | VCTRL1 | I1 is the control input pad for port RF1. Control voltages applied to this pad and the I2 pad will result in the active switch path being turned ON or OFF as described in the Application Information section of the datasheet. Nominal positive and negative control voltage for this port are +5V and -5V respectively. The bias circuit attached to this pad should be capable of sourcing or sinking at least 10mA of DC control current. | - |
| I2 | VCTRL2 | I2 is the control input pad for port RF2. Control voltages applied to this pad and the I1 pad will result in the active switch path being turned ON or OFF as described in the Application Information section of the datasheet. Nominal positive and negative control voltage for this port are +5V and -5V respectively. The bias circuit attached to this pad should be capable of sourcing or sinking at least 10mA of DC control current. | - |
| RF1 | Input/Output 1 | RF port 1 of the device, impedance looking into this port matches RFC load impedance in the ON state. This port is reflective and shorted to GND in the OFF state. This port is internally DC shorted to GND and should have an external DC block installed if DC exists on the RF1 line. | - |
| RF2 | Input/Output 2 | RF port 2 of the device, impedance looking into this port matches RFC load impedance in the ON state. This port is reflective and shorted to GND in the OFF state. This port is internally DC shorted to GND and should have an external DC block installed if DC exists on the RF2 line. | - |
| RFC | Common | RF common port of the device. The input impedance of this port is determined by the RF output port terminations. Output ports should be connected to a 50 Ohm load for normal operation. This port is internally DC shorted to GND and should have an external DC block installed if DC exists on the RFC line. | - |
