Description
The Skyworks SKY85408-11 is a 5
GHz
Microwave Monolithic
Integrated Circuit (MMIC) power amplifier (PA) with superior
output power, linearity, and efficiency. These features make the
SKY85408-11 ideal for Wireless Local Area Network (WLAN)
IEEE 802.11ax applications.
The SKY85408-11 features an internal band-gap regulator that
eliminates the need for an external reference supply. The PA is
activated with a standard 1.8 V to 5.0 V low current CMOS logic
signal.
The device is fabricated using Indium
Gallium
Phosphide (InGaP)
Heterojunction Bipolar Transistor (HBT) technology. The device is
internally matched and mounted in a 20-pin, 4 x 4 mm laminate
surface-mount technology (SMT) package, which allows for a
highly manufacturable, low-cost solution.
A block diagram of the SKY85408-11 is shown in Figure 1.
