Overview
The AD6630ARZ-REEL, manufactured by Analog Devices Inc., is an IF (Intermediate Frequency) gain block designed to interface between SAW (Surface Acoustic Wave) filters and differential input analog-to-digital converters. This component is optimized for use in narrow-band cellular and PCS (Personal Communications Service) receivers, particularly in the frequency range of 70 MHz to 250 MHz. The AD6630ARZ-REEL features a fixed gain of 24 dB and is built using Analog Devices’ high-speed complementary bipolar process, ensuring high linearity and low noise performance.
