Description
RF Input/Output – RF input/output with
50 Ω nominal impedance. An internally
generated DC voltage is present at this pin,
so an external DC block must be used to
connect this pin to the external circuit.
Equipotential Point – Internal circuit com-
mon, which must be connected to the pcb
ground or common via the lowest possible
impedance.
RF Output/Input – DC supply voltage input
and RF output/input with 50 Ω nominal
impedance. The nominal voltage required
at this pin is listed in the Specifications
table. Supply current must be limited by
an external resistor connected between the
DC power supply and this pin.
Control Voltage 1 – High input-impedance
control port for the 8 dB bit. The high control
voltage applied to this pin must be within
0.2 V of the supply voltage applied to pin
3, or the part may be permanently damaged.
The low control voltage is 0 V nominal.
No internal connection
Control Voltage 2 – High input-impedance
control port for the 4 dB bit. The high control
voltage applied to this pin must be within
0.2 V of the supply voltage applied to pin
3, or the part may be permanently damaged.
The low control voltage is 0 V nominal.

Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
CAUTION: Although this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
