Description
The SKY13374-397LF is a CMOS silicon-on-insulator (SOI) single-
pole, double-throw (SPDT) WCDMA band switch. The
high-linearity performance and low insertion loss achieved by the
device makes it an ideal choice for medium to high power
WCDMA handset and data card applications.
The high 0.1 dB input compression point (IP0.1dB) and advance
proprietary fabrication process enable exceptional WCDMA
harmonic and adjacent channel power (ACP) performance.
Excellent insertion loss and isolation is maintained over WCDMA
bands 1 to 6 and 8 to 11.
The SKY13374-397LF SPDT switch is provided in a compact
Quad Flat No-Lead (QFN) 2 x 2 mm package with 0.5 mm lead
pitch for ease of manufacturing. 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: Exposed pad must be properly grounded using a low impedance path.
Functional Description
Switching is controlled by two control voltage inputs (V1 and V2).
Depending on the logic voltage level applied to these pins, the
RF1 pin is connected to one of two switched RF outputs (RF2 or
RF3) using a low insertion loss path, while the path between the
RF1 pin and the other RF path is in a high isolation state.
An internal negative voltage generator and decoder eliminate the
need for external DC blocking capacitors on the RF ports. No
external components are required for proper operation. DC
decoupling capacitors may be added on the VBATT and control
lines if necessary.
Shutdown mode is enabled by connecting both control pins (V1
and V2) to logic low. This mode reduces the overall current
consumption of the device to 5 μA typical.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY13374-397LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
The state of the SKY13374-397LF is determined by the logic
provided in Table 4.
Typical performance characteristics of the SKY13374-397LF are
illustrated in Figures 3 through 5.

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.
