PRELIMINARY DATA SHEET SKY13448-001: 0.1 3.0 GHz SPDT High Power Switch (Single Bit Control) in a WLCSP Package Applications LTE TDD/FDD transmit/receive GSM transmit Embedded modules Features Broadband frequency range: 0.1 to 3.0 GHz Low insertion loss: 0.5 dB 2.7 GHz High isolation: 25 dB up to 2.7 GHz No external DC blocking capacitors required Single GPIO control line with VDD voltage regulator: VCTL = 1.65 to 2.70 V VDD = 2.45 to 3.00 V Figure 1. SKY13448-001 Block Diagram Small, 8-bump WLCSP, 200 m diameter, 400 m pitch (1.1 x 1.1 x 0.36 mm) package (MSL1, 260 C per JEDEC J-STD-020) Description The SKY13448-001 is a Single-Pole, Double-Throw (SPDT) LTE/WCDMA/GSM transmit switch. Switching is controlled by an integrated GPIO interface with a single control pin. Depending on the logic voltage level applied to the control pin, the antenna port is connected to one of the switched RF outputs (RF1 or RF2) through a low insertion loss path, while the path between the antenna port and the other RF port is in a high isolation state. No external DC blocking capacitors are required as long as no DC voltage is applied on any RF path. The SKY13448-001 is provided in a compact 8-bump, 1.1 x 1.1 x 0.36 mm Wafer Level Chip Scale Package (WLCSP) that meets requirements for board-level assembly. Bump diameters are 200 microns with a minimum bump pitch of 400 microns. 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. Figure 2. SKY13448-001 Pinout (Top View, Bumps Facing Down) Skyworks Solutions, Inc.

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. The state of the SKY13448-001 is determined by the logic Electrical and Mechanical Specifications provided in Table 8. The absolute maximum ratings of the SKY13448-001 are provided in Table 2. Electrical specifications are provided in Tables 3 through 7. Skyworks Solutions, Inc.
