DESCRIPTION
The RTC6669 is a high linearity power amplifier (PA) designed specially for high power application. The device is manufactured based on advanced GaAs HBT(Hetero-junction Bipolar Transistor) process and designed for operating in 2.4~2.5GHz frequency range, compatible with 802.11b/g/n wireless LAN system. The amplifier consists of 3 gain stages with inter-stage matching, build-in input matching network, and a power detector for close loop power control operation. In 802.11g mode (OFDM 64QAM, 54Mbps), it provides a low EVM (Error-Vector magnitude) of 3% at +23.5dBm linear output power. 30.5dB gain is achieved with quiescent current 440mA. The device is provided in a tiny industry-standard 16-lead surface mount package QFN 3mmX3mm.
Application
◆ High Power WLAN applications
◆ IEEE 802.11b/g/n Wireless LAN System
◆ 2.4GHz ISM Band Application
◆ 2.4GHz Cordless Phones
