Description
Features
The RTC6659E is a power amplifier (PA) designed for 4.9 ~ 5.9 GHz
frequency range, compatible with 802.11a wireless LAN system.
The device is manufactured based on advanced InGaP/GaAs HBT
(Heterojunction Bipolar Transistor) process. The amplifier consists
of 3 gain stages with inter-stage matching, built-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 +22 dBm linear output power In 802.11a mode
(OFDM 64QAM, 54Mbps). The RTC6659E is packaged in a tiny
industry-standard 16-lead surface mount package QFN 3mm x 3mm x
1mm (max) with lead-free RoHS compliant.
