Description
The SKY13575-639LF is a dual-band single-pole, four-throw
switch with an integrated 50 match on all RF output ports.
External DC blocking capacitors are required on the RF paths. The
switch can operate over the temperature range of -40C to 90 C.
Switching is controlled by two CMOS/TTL compatible control
voltage inputs: VC1 and VC2. Depending upon the logic voltage
level applied to the control pins, the RFC pin is connected to one
of four switched RF outputs (RF1 to RF4) by a low insertion loss
path, while the path between the RFC pin and the other RF pins is
in isolation. The isolated ports are terminated to a 50 load.
The SKY13575-639LF is packaged in a small, 14-pin,
1.6 1.6 0.45 mm 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 descriptions are provided in Table 1.

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.
ESD HANDLING: 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 when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.
