DESCRIPTION
The RTC6685 silicon-germanium (SiGe) power amplifier (PA) is designed to operate in 2.4GHz ISM band, compatible with 802.11b/g wireless LAN system and Bluetooth class 1 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 802.11g mode (OFDM 64QAM, 54Mbps), it provides a low EVM (Error-Vector magnitude) of 3% at +18.5dBm linear output power. The device is packaged in a tiny industry-standard 8-lead surface mount package SLP 8L 2x2.
