Description
The SKY13335-381LF is a pHEMT GaAs FET I/C switch. The
device features low insertion loss and positive voltage operation
with very low DC power consumption. The switch is manufactured
in a compact, low-cost 1.5 x 2.0 mm, 6-pin Micro Leadframe
Package Dual (MLPD) package.
The switch can be used in transmit/receive applications by
connecting the RF common port (RFC, pin 5) to either the OUT1 or
OUT2 port (pins 1 or 3, respectively) using a low-loss path (i.e., a
positive voltage applied to either the VCTL1 or VCTL2 pins). The
switch is a reflective short on the isolated port.
A functional block diagram is shown in Figure 1. The 6-pin MLPD
package and pinout are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.

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.
