LT5522EUF#TRM

RF Mixers Overview

The LT5522EUF#TRM is a high signal level downconverting mixer from Analog Devices Inc., designed for RF applications. It operates within a frequency range of 400MHz to 2.7GHz. The device features a noise figure of 13.9dB and a gain of -0.2dB. It requires a supply voltage between 4.5V and 5.25V, with a typical supply current of 56mA. The component is housed in a 16-pin QFN-EP package suitable for surface mount mounting. It supports cellular, PCS, and UMTS RF types and functions effectively across an operating temperature range of -40°C to 85°C.

RF Mixers Feature Summary

• Integrates a high-speed differential local oscillator buffer amplifier internally matched for broadband single-ended operation without external components.
• Includes an integrated RF transformer at the radio frequency input port.
• Designed for high signal level downconversion capabilities.

RF Mixers Applications

• Cellular communication systems
• PCS (Personal Communications Service) applications
• UMTS (Universal Mobile Telecommunications System) receivers

RF Mixers Procurement Notes

Verify that the specific suffix #TRM indicates tape and reel packaging rather than tube packaging when sourcing this component. Confirm the manufacturer is Analog Devices Inc. or its authorized predecessor Linear Technology. Ensure the part number matches the exact electrical specifications provided in the official datasheet to avoid confusion with similar models like the LT5522EUF#PBF which may have different packaging configurations.

RF Mixers Selection Notes

Select this component for designs requiring downconversion in the 400MHz to 2.7GHz range. Consider the 56mA supply current and 4.5V to 5.25V voltage requirements for power budgeting. The 16-QFN package size should be evaluated against available PCB space. Verify compatibility with the intended LO drive levels and RF input signal characteristics for optimal performance in cellular or PCS environments.

RF Mixers Part Context

This mixer belongs to the LT5522 family of high-performance RF mixers. It shares functional similarities with other devices in the series but differs in specific packaging options such as the tape and reel variant indicated by the TRM suffix. It is distinct from quadrature modulators like the LT5528, serving primarily as a downconverter rather than a modulator/demodulator pair.

RF Mixers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The LT5522EUF#PBF is a related variant differing primarily in packaging type.
