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 SiGe BiCMOS 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 compliant with
all applicable legislation and are halogen-free.
