SKY85601-21 Block Diagram High IIP3: +6 dBm High gain: 12 dB Description Bypass mode with 5 dB insertion loss The SKY85601-21 is an integrated, single-pole double-throw High transmit to receive isolation for high power applications (SPDT) switch with a low-noise amplifier (LNA) intended for wireless applications. The device has a low noise figure (NF) with Small QFN (16-pin, 2.5 x 2.5 mm) package high linearity in the transmit mode. (MSL1, 260 C per JEDEC J-STD-020) The SKY85601-21 operates at 3.3 V and draws 15 mA of current. TM Skyworks Green products are compliant with In the transmit mode, a shutdown function saves power when the all applicable legislation and are halogen-free. device is inactive. The switch requires five external components. For additional information, refer to Skyworks TM The switch is manufactured in a compact, 2.5 x 2.5 mm, 16-pin Denition of Green , document number Quad Flat No-Lead (QFN) package. The small footprint provides SQ040074. the industrys smallest PCB area needed to implement an integrated broadband SPDT switch with LNA functionality. 16 15 14 13 A functional block diagram is shown in Figure 1.

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. Table 3.
