LTC6602IUF#PBF

Overview

The LTC6602IUF#PBF 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 selectivity of the LTC6602, combined with its phase matching and dynamic range, make it ideal for filtering in RFID systems. With two degree phase matching between channels, the LTC6602 can be used in applications requiring highly matched filters, such as transceiver I and Q channels. Gain programmability, and the fully differential inputs and outputs, simplify implementation in most systems.

Feature Summary

• Dual Matched Filter/Driver, Ideal for RFID Readers
• Guaranteed Phase Matching to Within 2 Degrees
• Configurable as Lowpass or Bandpass: Programmable 5th Order Lowpass: 42kHz to 900kHz; Programmable 4th Order Highpass: 4.2kHz to 90kHz
• Programmable Gain: 1×, 4×, 16×, 32×

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to ensure correct temperature grade and packaging configuration. Confirm that the component meets all RoHS compliance requirements before integration into final assemblies. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity.

Selection Notes

Select the LTC6602IUF#PBF when an industrial temperature range from -40°C to 85°C is required. Verify that the 24-lead QFN package fits within the available PCB footprint constraints. Ensure the system design accommodates the necessary external resistor for oscillator frequency setting if internal clocking is utilized. Confirm that the supply voltage range aligns with the system's power distribution network capabilities.

Part Context

The LTC6602IUF#PBF belongs to the LTC6602 family of dual matched high-frequency bandpass/lowpass filters. This series is designed for applications requiring precise phase and gain matching between channels. The 'IUF' designation indicates the industrial temperature grade and the 4mm x 4mm QFN package type. The '#PBF' suffix denotes lead-free finish and RoHS compliance.

Replacement Considerations
