Description
The SKY13395-397LF is a GaAs pHEMT double-pole, doublethrow (DPDT) switch. The switch provides high linearity
performance, low insertion loss, and high isolation.
Switching is controlled by two voltage inputs (CTRL1 and CTRL2).
Depending on the logic voltage level applied to these pins, the
PORT1 and PORT2 pins connect to one of the two other RF port
pins (PORT3 or PORT4) through a low insertion loss path, while
maintaining a high isolation path to the alternate port.
The SKY13395-397LF DPDT switch is provided in a compact Quad
Flat No-Lead (QFN) 2 x 2 mm 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 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.
Functional Description
Electrical and Mechanical Specifications
The SKY13395-397LF DPDT switch can be used to connect either
RF port 1 or RF port 2 to either RF port 3 or RF port 4 by applying
the proper bias to the two control pins (CTRL1 and CTRL2). When
Port 1 is connected to Port 4 using a low loss path, Port 2 is
connected to Port 3 also with a low loss path. When Port 1 is
connected to Port 3 using low loss path, Port 2 is connected to
Port 4 also with a low loss path.
The absolute maximum ratings of the SKY13395-397LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
The DPDT switch is designed to maximize the isolation between
ports to minimize coupling between RF paths.
The state of the SKY13395-397LF is determined by the logic
provided in Table 4.
Typical performance characteristics of the SKY13395-397LF are
illustrated in Figures 3 through 7.
