SKY14151-350LF Block Diagram to 1.8 V for low power applications High linearity IMD < 111 dBm over phase Description Good harmonic performance < 80 dBc 0.9 GHz The SKY14151-350LF is a symmetrical, single-pole, four-throw Low voltage logic compatible (minimum VHIGH = 1.8 V) (SP4T) switch. The device is designed for broadband, high power Small, QFN (16-pin, 3 x 3 mm) package (MSL1, 260 C per switching applications that demand high linearity and low JEDEC J-STD-020) insertion loss. This is a general purpose switch optimized for a variety of multimode applications such as GSM/WCDMA/EDGE. The switch is manufactured using Skyworks state-of-the-art pHEMT process. The SKY14151-350LF features integrated logic that uses only two control lines for switch operation. The low current consumption makes the device suitable for battery- operated applications. The SKY14151-350LF SP4T switch is provided in a compact Quad Flat No-Lead (QFN) 3 x 3 mm package. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2.

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.
