Use the RF212 device instead (Data Sheet No. 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 Amplifiers (LNAs), two image-reject mixers, and two Local Oscillator (LO) buffer amplifiers. The main advantage of the RF210A and RF210B is their ability to provide 30 dB of image rejection for both the GSM900 and the DCS1800 (or PCS1900) bands without requiring the use of a post-LNA image reject filter. A block diagram of the RF210(A/B) is shown in Figure 1. The device package and pin configuration are shown in Figure 2. Features • LNA/image-reject mixer for RF to IF conversion • 10 dB (RF210A) or 20 dB (RF210B) switchable gain for GSM • 8 dB (RF210A) or 16 dB (RF210B) switchable gain for DCS/PCS • 30 dB of image rejection. No post-LNA filtering required • High isolation LO input buffer • Differential IF output • High dynamic range • Three-cell battery operation (2.7 to 5 V) • 20-pin Thin Shrink Small Outline Package (TSSOP) Applications • Dual-band digital cellular mobile telephony (GSM900/DCS 1800 or GSM900/PCS1900) LNA900IN C069 0 90 90 LNA1800IN GAINSEL IFOUT LOIN IRM BIAS BANDSEL BYP900 BYP1800 0 90 Figure 1.
