LTC6602IUF#TRPBF

Overview

The LTC6602IUF#TRPBF is a dual, matched, programmable bandpass or lowpass filter and differential driver manufactured by Analog Devices Inc. It operates on a single 2.7V to 3.6V supply and features a low power shutdown mode. The device offers configurable gain settings of 1x, 4x, 16x, and 32x (0dB, 12dB, 24dB, 30dB). Filter cutoff frequencies are set with a guaranteed accuracy of 3% using a single resistor or controlled via an external clock. It provides fully differential inputs and outputs with rail-to-rail capability.

Feature Summary

• Dual matched channels with guaranteed phase matching within 2 degrees and gain matching within 0.2dB
• Configurable as lowpass or bandpass with programmable gain and simple pin programming or SPI interface
• Low noise performance with input referred noise as low as -145dBm/Hz and low distortion characteristics
• Differential, rail-to-rail inputs and outputs with input range extending from 0V to 5V

Applications

• UHF RFID Reader Dual Baseband Filter and Dual ADC
• Multiprotocol RFID Readers including EPC-GEN2, ISD and IPX
• IDEN, PHS, GSM Basestations
• Repeaters, Radio Links, and Modems
• Wireless Telemetry and JTRS systems

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the IUF variant meets the specified temperature range requirements for your application environment. Ensure compatibility with the required voltage supplies and interface protocols before finalizing procurement decisions.

Selection Notes

Select the LTC6602IUF#TRPBF for applications requiring highly matched filters such as transceiver I and Q channels. Consider the internal oscillator or external clock options based on frequency stability needs. Evaluate the available gain settings and filter configurations to ensure they align with the system's dynamic range and bandwidth specifications.

Part Context

This component belongs to the LTC6602 series of dual matched high-frequency bandpass/lowpass filters. It is designed for use in systems where phase and gain matching between channels are critical. The device integrates programmable filters and a differential driver in a compact 4mm x 4mm QFN package.

Replacement Considerations

Consult Analog Devices marketing for parts specified with wider operating temperature ranges if the current specification is insufficient.
