The AD6650 is a diversity intermediate frequency-to-baseband (IF-to-baseband) receiver for GSM/EDGE.
The AD6650 is a diversity intermediate‑frequency‑to‑baseband receiver designed for GSM/EDGE applications. It integrates a digital VGA, I/Q demodulators, low‑pass filters, and dual wideband ADCs, supporting IF inputs from 70 MHz to 260 MHz. The device includes programmable decimation and channel filters, a VCO/PLL, and serial data output ports.
Key specifications include a 116 dB dynamic range, 10 dB noise figure, +43 dBm input IP2, –9.5 dBm input IP3, and a 3.3 V power supply. The AD6650 is suited for PHS/GSM‑EDGE single‑carrier diversity receivers, microcell and picocell systems, wireless local loop, smart antenna systems, software radios, and in‑building wireless telephony.

The AD6650 operates from 70 MHz up to 260 MHz.
It is used in PHS or GSM/EDGE single‑carrier diversity receivers, microcell and picocell systems, wireless local loop, smart antenna systems, software radios, and in‑building wireless telephony.
Both AVDD and DVDD must be 3.3 V, with a valid range of 3.0 V to 3.45 V.
Input IP2 is +43 dBm at 70 MHz IF, and input IP3 is –9.5 dBm at 70 MHz IF.
