DESCRIPTION
The RTC6649E is a power amplifier (PA) designed for 2.
4~2.
5GHz frequency range, compatible with 802.
11b/g/n 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.
In 802.
11g mode (OFDM 64QAM, 54Mbps), it is capable to provide a low EVM (Error-Vector magnitude) of 3% at +26dBm and 23.
5dBm linear output power by single supply voltage 5V and 3.
3V, respectively.
The device is provided in a tiny industrial standard 16-...
