SKY65152-11: 2.4-2.5 GHz WLAN Power Amplifier
Applications
IEEE 802.11 b/g WLANs
ISM band transmitters
WCS fixed wireless
Wireless access nodes
Description
The SKY65152-11 is a Microwave Monolithic Integrated Circuit
(MMIC) Power Amplifier (PA) with superior output power, linearity,
and efficiency. These features make the SKY65152-11 ideal for
Wireless Local Area Network (WLAN) applications. The high
linearity (low EVM) and high efficiency of this device makes it
ideal for use in the transmit chain of WLAN access points or
modems.
The SKY65152-11 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 and
mounted in a 20-pin, 6 x 6 mm Multi-Chip Module (MCM)
Surface-Mounted 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
Table 1.
