RTC6689H
V0.2
Data Sheet
March 2005
DESCRIPTION
The RTC6689H silicon-germanium (SiGe) power amplifier (PA) is designed to operate
in 2.4GHz ISM band, compatible with 802.11b/g wireless LAN system. The Amplifier
consists of 3 gain stages with inter-stage matching and build-in input matching network,
and a power detector for close loop power control operation. In 802.11g mode (64QAM,
54Mbps), it provides a low EVM (Error-Vector magnitude) of 3% at +19dBm linear
output power. The device is packaged in a tiny industry-standard 16-lead surface mount
package QFN16 3x3.
FEATURE
◆ 3.3V Power Supply
◆ Maximum Linear Output Power for 11g usage : +19dBm OFDM
◆ Maximum Linear Output Power for 11b usage : +20 dBm QPSK
◆ Small signal gain : 32dB
◆ On-chip input matching
◆ Operation ambient temperature: -40 ~ +120 °C
APPLICATION
◆ IEEE 802.11b/g Wireless LAN Application
◆ Wireless Local Area Networks (WLAN)
◆ ISM System including Automatic Level Control(ALC)
◆ TDMA Packet Protocol Radios
