DESCRIPTION
The RTC6667E is a RF front-end module (FEM) designed for 802.11 b/g/n WLAN applications. This device consists of a power amplifier (PA), a SPDT switch (SW), a band pass filter (BPF), and a balun (BAL). The module is designed to operate in 2.4 GHz ISM band, compatible with 802.11 b/g/n wireless LAN system with low loss, and large output power. All inputs and outputs are internally matched to 50Ω and the WLAN received terminal is a differential port with impedance of 200Ω. In the transmitting path, the FEM has a typical gain of 24 dB from 2.4 GHz to 2.5 GHz, and delivers 17 dBm typical output power under 3% EVM OFDM 54Mbps modulation. In the transmitting path, the FEM possesses 30 dBc high out-band suppression at 1.9 GHz and thus suitable for mobile handset application. In the receiving path, the typical insertion loss is 3.1 dB for 200Ω differential output port. These features make RTC6667E FEM very useful in various applications, such as hand-held device and battery-powered WLAN equipment. The RTC6667E is packaged in a tiny industry-standard 16-lead surface mount package VQFN 4 X 4 mm2 with lead-free RoHS compliant.
