Description
The SKY13372-467LF is a GaAs pHEMT FET high-isolation,
absorptive switch. The device is an ideal component for base
station applications in which synthesizer isolation is critical.
The device is provided in a 4 x 4 mm, 16-pin Quad Flat No-Lead
(QFN) package. A functional block diagram is shown in Figure 1.
The pin configuration and package are shown in Figure 2. Signal
pin assignments and functional pin descriptions are provided in
Table 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.
