RF210B Overview
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.
RF210B Key Features

- 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)
