DESCRIPTION
The RTC6670E power amplifier (PA) is designed to operate in 5GHz ISM band, compatible with 802.11a wireless LAN system with high power, high gain. 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 802.11a mode (OFDM 64QAM, 54Mbps), it provides a low EVM (Error Vector Magnitude) of 3% at +19dBm linear output power. The part is pin compatible to previous RTC6670 with performance enhancement. The device is packaged in a tiny industry-standard 16-lead surface mount package QFN16 3x3.
Application
◆ IEEE 802.11a Wireless LAN System
◆ 5GHz ISM Band Application
◆ 5GHz Cordless Phones
◆ High Power WLAN applications
