The AD6630 is a differential, low noise IF gain block with features such as 24dB gain, 4dB noise figure, easy match to SAW filters, and adjustable output limiter.
The AD6630 is a differential, low‑noise IF gain block designed to interface SAW filters with ADCs. It provides a fixed 24 dB gain, 4 dB noise figure, and adjustable output limiting from +8.5 dBm to +12 dBm across a 70 MHz to 250 MHz bandwidth.
The device is supplied in a 16‑lead wide‑body SOIC package, operates from a single 10 V supply (8.5‑10.5 V typical), and is rated for –40 °C to +85 °C. Detailed specifications, pin descriptions, and reference designs are included for RF designers.
