RTC6671

RICHWAVE CONFIDENTIAL T-ST-6671-DST-001 Data Sheet RTC6671 Aug 2008 DESCRIPTION The RTC6671 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 +18dBm 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 11a usage : +18 dBm ( 54Mbps OFDM 64 QAM ) ◆ Small signal gain : 28dB ◆ On-chip input matching ◆ Operation ambient temperature: -40 ~ +85 °C ◆ Lead(Pb)-free, RoHS compliant packaging APPLICATION ◆ IEEE 802.11a Wireless LAN System ◆ 5GHz ISM Band Application ◆ 5GHz Cordless Phones ◆ High Power WLAN applications ...
