Functional Description
Switching is controlled by two control voltage inputs (V1 and V2).
Depending on the logic voltage level applied to these pins, the
RF1 pin is connected to one of two switched RF outputs (RF2 or
RF3) using a low insertion loss path, while the path between the
RF1 pin and the other RF path is in a high isolation state.
An internal negative voltage generator and decoder eliminate the
need for external DC blocking capacitors on the RF ports. No
external components are required for proper operation. DC
decoupling capacitors may be added on the VBATT and control
lines if necessary.
Shutdown mode is enabled by connecting both control pins (V1
and V2) to logic low. This mode reduces the overall current
consumption of the device to 5
μA
typical.
Electrical and Mechanical Specifications

Note 1:
Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION:
Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
