Description

The SKY65900-11 is a Microwave Monolithic Integrated Circuit

(MMIC) Power Amplifier (PA) with superior output power, linearity,

and efficiency. These features make the SKY65900-11 ideal for

Wireless Local Area Network (WLAN) applications. The high

linearity (low EVM) and high efficiency of this device make it ideal

for use in the transmit chain of WLAN access points or modems.

The SKY65900-11 is fabricated using Skyworks high reliability

Heterojunction Bipolar Transistor (HBT) InGaP process, which

allows for single supply operation while maintaining high

efficiency and good linearity. The device is internally matched at

the RF input and mounted in a 16-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 functional block diagram is shown in Figure 1. The pin

configuration and package are shown in Figure 2. Signal pin

assignments and functional pin descriptions are provided in
