FX6779（5G射频前端解决方案）

Description

Packaged in a 4.5mm x 5.5mm x 0.825mm(Typ. ) module, the FX6779 perform with 

high efficiency, high linearity, low temperature variation, strong reliability and robust 

ruggedness. In addtion to the feature of RoHS compliant, the FX6779 is free of 

hazardous substances and rated as green product.

FX6779 is a 42-pin Power Amplifier Module developed for 5G-NR standards. With 

advanced InGap HBT, SOI and LTCC technology, the module supports multibands

(B42/B43/B48/n77/n78/n79) LTE/NR applications. The FX6779 meets stringent 

linearity requirements of DFTS-OFDM and CP-OFDM specifications at APT

(Average Power Tracking) Power Class 2(PC2) power targets.

The FX6779 is self contained with two GaAs PAs and filters, a CMOS controller with a 

MIPI 2.1 core integrated, a SOI switches for antenna Tx-Rx and coupler forward-Reverse 

switching, a Low Noise amplifier(LNA) with a MIPI 2.1 core integrated and input/output 

matching network.

With Lansus's state-of-art technology and optimized bias table, the FX6779 reduces 

current consumption significantly in both high and low power operations. Compatible 

with APT technology to extend battery life, the FX6779 efficiency can be further improved.
