The RDA6625 is a quad-band power amplifier module built for GSM850, EGSM900, DCS1800, and PCS1900 phone boards. You get a compact 5mm × 5mm × 1.1mm LGA chip that combines power amp lification and antenna switching in one package. GaAs HBT construction handles the RF amplification while a CMOS controller manages switching logic, giving you stable transmit power without extra external circuitry. This IC replaces burnt or dead PA chips causing no network, weak signal, or "network issue" complaints on affected boards. A reliable pick for your repair bench when signal-related faults trace back to the PA stage. Show more
