DESCRIPTION
The RTC6659E is a power amplifier (PA) designed for 4.9~5.9GHz frequency range, compatible with 802.11a wireless LAN system. The device is manufactured based on advanced InGaP/GaAs HBT (Hetero-junction Bipolar Transistor) process. 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. With single supply voltage 5V, it provides a low EVM (Error-Vector magnitude) of 3% at +22dBm linear output power In 802.11a mode (OFDM 64QAM, 54Mbps). The device is provided in a tiny industry standard 16-lead surface mount package QFN 3mmX3mm.
