2.4 GHz High-Gain, High-Efficiency Power Amplifier
SST12LP19E
SST12LP19E is a versatile power amplifier based on the highly-reliable InGaP/
GaAs HBT technology. SST12LP19E is a 2.4 GHz fully-integrated, high-power,
high-gain Power Amplifier module designed in compliance with IEEE 802.11b/g/n
and 256 QAM applications. For WLAN applications, it typically provides 25 dB gain
with 34% power-added efficiency. SST12LP19E has excellent linearity while meet-
ing 802.11g spectrum mask at 23.5 dBm and 802.11b spectrum mask at 23 dBm.
This power amplifier includes a power detector with dB-wise linear voltage output
and features easy board-level usage along with high-speed power-up/down control
through a single combined reference voltage pin. SST12LP19E and is offered in 6-
contact XSON, 8-contact XSON, and 6-contact X2SON packages. Due to its small
package size and high efficiency, this power amplifier is also well suited for ZigBee
®
and Bluetooth
®
applications.
