SKY85402-11 Datasheet | Skyworks Solutions

Features - Linear output power for IEEE 802.11ac 256-QAM, EVM < 1.8% = +22 d Bm @ 5.0 V - High gain: 32 d B - Power shutdown mode - Superior gain flatness - Fully matched at RF input/output ports - Load insensitive power detector - Small footprint QFN (20-pin, 4 x 4 mm) SMT package (MSL3, 260 C per JEDEC J-STD-020) Description Skyworks SKY85402-11 is a 5 GHz Microwave Monolithic Integrated Circuit (MMIC) power amplifier (PA) with superior output power, linearity, and efficiency. These features make the SKY85402-11 ideal for wireless local area network (WLAN IEEE 802.11ac) applications. The device is fabricated using Si Ge Bi CMOS technology. The device is internally matched and mounted in a 20-pin, 4 x 4 mm Quad Flat No-Lead (QFN) surface-mount technology (SMT) package, which allows for a highly manufacturable low cost solution. A block diagram of the SKY85402-11 is shown in Figure 1.The device package and pinout are shown in Figure 2. Signal pin assignments and functional pin descriptions are described in Table 1. Skyworks Green TM products are pliant with all applicable legislation and are halogen-free. For additional information, refer to Skyworks Definition of Green TM, document number SQ04- 0074.
