The chip is a dual-band mobile phone RF front-end module with high power efficiency. It was an early-stage flagship product of RDA and broke the foreign monopoly in the field of GaAs commercial power amplifier. It perfectly fits in with 2G communication frequency bands, such as GSM850, EGSM900, DCS1800 and PCS1900. It features 5mm*5mm*1.1 LGA packaging and is the smallest front-end module of its kind. The chip also applies advanced IPD technology, which cuts costs and increases competitiveness. It has been widely recognized by the domestic market. More than 100 million chips have been sold to date.
