AD607ARS

Overview

The AD607ARS is a low-power receiver intermediate frequency (IF) subsystem designed for operation at input frequencies up to 500 MHz. It supports IFs ranging from 400 kHz to 12 MHz and operates on a single 3 V supply. The device integrates a mixer, linear IF amplifiers, I and Q demodulators, a phase-locked quadrature oscillator, and an automatic gain control (AGC) detector. It features a Monoceiver architecture with a -15 dBm 1 dB compression point and -8 dBm input third-order intercept. Power consumption is 25 mW at 3 V, and it includes CMOS-compatible power-down interfaces.

Feature Summary

• Integrates complete receiver-on-a-chip functionality including mixer, IF amplifiers, and demodulators
• Features a linear-in-dB gain control system with manual gain adjustment capabilities
• Includes an on-board phase-locked quadrature oscillator for demodulation
• Supports low power operation with dedicated power-down interfaces

Applications

• GSM, CDMA, TDMA, and TETRA receivers
• Satellite terminals
• Battery-powered communications receivers

Procurement Notes

Verify the specific suffix ARS against official Analog Devices documentation to confirm package type and temperature range. Confirm current availability status as distribution channels may list limited stock or obsolete status. Ensure compatibility with required baseband converters such as AD7013 or AD7015 if interface integration is planned. Check for RoHS compliance details in the latest datasheet revision.

Selection Notes

Select this component for applications requiring a compact analog solution in the audio and video domain. It is suitable for designs needing integrated RF mixing and IF processing without external discrete components. Consider the 3 V operating voltage constraint and the need for external components for biasing and power-down control. Evaluate the 500 MHz bandwidth requirement against the target signal frequency.

Part Context

The AD607 belongs to the AD607 family of receiver IF subsystems manufactured by Analog Devices. It is part of the broader portfolio of wireless and RF integrated circuits designed for mobile communication standards. The device serves as a key building block for multi-standard radio front ends, offering high integration to reduce board space and complexity in portable devices.

Replacement Considerations

Public confirmed substitutes include the AD608, which offers similar low-power characteristics with added RSSI and limiter functions. The AD6458 and AD6459 are also listed as related GSM-focused 3 V receiver IF subsystems from the same manufacturer.
