LT5527EUF

RF Mixers Overview

The LT5527EUF is an active RF mixer from Analog Devices, designed for high linearity and wide dynamic range downconversion. It operates with an RF frequency range of 400 MHz to 3.7 GHz and a local oscillator (LO) frequency of 380 MHz to 3.5 GHz. The intermediate frequency (IF) spans 100 kHz to 600 MHz. Key electrical parameters include a noise figure of 16.1 dB, a P1dB compression point of 9 dBm, and an OIP3 of 18.2 dBm. The device features a gain of 0.3 dB and draws 78 mA at a supply voltage of 4.5 V to 5.25 V. It is housed in a QFN-16 package and functions within a temperature range of -40°C to +85°C.

RF Mixers Feature Summary

• High isolation between LO-RF and LO-IF ports
• Optimized for high linearity and wide dynamic range applications

RF Mixers Applications

• Cellular infrastructure downconverters
• WCDMA and UMTS receiver front-ends
• MMDS signal processing systems
• TD-SCDMA communication modules

RF Mixers Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability records for the Analog Devices component. Cross-reference the exact part number against current distributor listings to confirm availability and authenticity before finalizing procurement plans.

RF Mixers Selection Notes

Select this component for applications requiring high signal level handling and wide bandwidth. The integrated LO buffer simplifies design by reducing external drive requirements. Consider the 16.1 dB noise figure and 18.2 dBm OIP3 for system sensitivity and linearity budgets. The QFN-16 package suits space-constrained PCB layouts. Evaluate thermal performance given the 78 mA operating current and +85°C maximum junction temperature limit.

RF Mixers Part Context

The LT5527 belongs to Analog Devices' portfolio of active mixers optimized for wireless communications. It serves as a direct replacement for older passive or active mixer solutions requiring higher input power handling. The EUF variant specifies the lead-free, halogen-free package configuration compliant with modern environmental standards. This series supports multi-standard radio architectures common in modern cellular base stations and user equipment.
