Description For additional information, refer to Skyworks The SKY13358-388LF is a GaAs pHEMT Single-Pole, Five-Throw Denition of Green, document number (SP5T) switch with an internal CMOS decoder. The high linearity SQ04-0074. performance and low insertion loss achieved by the SKY13358- 388LF make it an ideal choice for cellular infrastructure applications. Switching is controlled by three CMOS/TTL compatible control voltage inputs (V1, V2, and V3). Depending on the logic voltage level applied to the control pins, the RFC (RF common) pin is 16 15 14 13 connected to one of five switched RF outputs (RF1, RF2, RF3, GND 1 12 RF4 RF4, or RF5) through a low insertion loss path while the path 2 11 between the RFC pin and the other RF pins is in a high isolation RF1 GND state. External DC blocking capacitors are required on the RF GND 3 10 RF5 paths. 4 RFC 9 GND The SKY13358-388LF is manufactured in a compact, 16-pin 5 6 78 2.3 x 2.3 mm Quad Flat No-Lead (QFN) package. A functional block diagram is shown in Figure 1. The pin S2308 configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Figure 2.

Functional Description The SKY13358-388LF is comprised of a CMOS decoder that When VDD is not applied, the device is considered off or inactive. enables three control lines and five RF ports. The decoder is All arms of the switch remain on in this state, creating a poor five- internally connected to a GaAs pHEMT RF switch. Depending on way power splitter. The return loss of all RF ports is very low in the logic voltage level applied to the control pins, the RFC pin is this state. RF should not be applied when VDD is not present and connected to one of five switched RF outputs (RF1, RF2, RF3, should only be used to conserve current. RF4, or RF5) by a low insertion loss path, while maintaining a high isolation path to the alternate ports. Electrical and Mechanical Specifications Startup time is defined as the time from when VDD is applied to The absolute maximum ratings of the SKY13358-388LF are when the switch is active. Once the startup time has passed, the provided in Table 2. Electrical specifications are provided in control voltages V1 and V2 can be applied. RF power should not Table 3. be applied during the startup time or damage to the device could result. Typical performance characteristics of the SKY13358-388LF are illustrated in Figures 3, 4, and 5. The recommended startup sequence is: The state of the SKY13358-388LF is determined by the logic Step 1: Apply VDD. provided in Table 4. Step 2: Apply V1, V2, and V3. Step 3: Apply RF input.
