RF210B, RF210A, (RF210A / RF210B) Image-Reject Downconverters
The RF210(A/B) dual-band, image-reject downconverters implement the front-end functions of a dual-band superheterodyne receiver.
These devices consist of two receive paths, one for GSM900 and the other for DCS1800 (or PCS1900).
Each receive path contains an LNA and an imagereject mixer.
The IF and L

100780) RF210A and RF210B Dual-Band, Image-Reject Downconverters For GSM Applications The RF210A and RF210B devices are available as a dual-band front end for Global System for Mobile Communications (GSM) handset applications.
Both of these highly integrated, monolithic devices are optimized for dual-band use in GSM900/DCS1800 or GSM 900/PCS1900 applications.
The devices include two Low Noise Amplifier
