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.
Functional Description
The SKY13392-359LF is comprised of a CMOS decoder that
enables two TTL-compatible DC lines to control four RF ports. The
decoder is internally connected to a GaAs pHEMT RF switch.
Depending on the logic voltage level applied to the control pins,
the RFC pin is connected to one of four switched RF outputs (RF1,
RF2, RF3, or RF4) by a low insertion loss path, while maintaining
a high isolation path to the alternate port.
The CMOS decoder should have V
DD
applied before a logic high is
applied to one of the control lines.
The recommended startup sequence is:
Step 1: Apply V
DD
.
Step 2: Apply VC1 and VC2
Step 3: Apply RF input.
The device must be turned off in the reverse order.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY13392-359LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
The state of the SKY13392-359LF is determined by the logic
provided in Table 4.
Typical performance characteristics of the SKY13392-359LF are
