Description
The SKY13366-378LF is a pHEMT GaAs FET I/C switch. The
switch may be used in transmit/receive applications by
connecting the RF common port (INPUT, pin 5) to either the
OUTPUT1 or OUTPUT2 port (pin 1 or 3, respectively) using a low
loss path (i.e., a positive voltage applied to either VCTL1 or VCTL2
pins). The switch is “reflective short” on the isolated port.
The switch is manufactured in a compact, 1 x 1 mm, 6-pin
exposed pad plastic Micro Leadframe Package Dual (MLPD)
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.

Note:
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.
