SKY65080-70LF Pinout - 4-Pin SOT Package High linearity: IIP3 = +25.5 dBm (Top View) Output P1dB = +21 dBm Description High gain: 15 dB Skyworks SKY65080-70LF is a high performance, ultra-wideband Single DC supply: +5 V power amplifier (PA) driver with superior output power, low noise, On-chip bias circuit linearity, and efficiency. The device provides a 2.3 dB noise figure SOT-89 (4-pin, 2.4 x 4.5 mm) package (NF) and an output power at 1 dB compression of +21 dBm, (MSL1, 260 C per JEDEC J-STD-020) making the SKY65080-70LF ideal for use in the driver stage of infrastructure transmit chains. The SKY65080-70LF uses low-cost surface-mount technology (SMT) in the form of a 4-pin, 2.4 x 4.5 mm small outline transistor TM Skyworks Green products are compliant with (SOT) package. The device package and pinout are shown in all applicable legislation and are halogen-free. Figure 1 and a functional block diagram is provided in Figure 2.
