AK1575

RF Mixers Overview

The AK1575 is an integrated RF mixer IC manufactured by Asahi Kasei Microdevices/AKM, designed for up-conversion applications. It operates within a frequency range of 690MHz to 4GHz and is housed in a 32-QFN (4x4) surface-mount package. The device requires a supply voltage between 4.75V and 5.25V and draws a typical supply current of 270mA. Key electrical specifications include a conversion gain of 1.5dB and a noise figure of 14dB. This component integrates a fractional-N frequency synthesizer and VCO core to support wide-band operation with low phase noise characteristics.

RF Mixers Feature Summary

• Integrates a fractional-N frequency synthesizer and VCO core for simplified system design
• Utilizes three overlapping VCO cores to achieve low phase noise and reduced sensitivity
• Supports wide frequency coverage from 690MHz to 4GHz in a compact surface-mount package

RF Mixers Applications

• RF up-converter modules
• Wireless communication systems requiring wideband frequency synthesis
• IoT sensor nodes with transmission capabilities

RF Mixers Procurement Notes

Verify part status carefully as the AK1575 is listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing PCB footprints and thermal requirements before procurement. Check for valid replacement components if long-term production support is required.

RF Mixers Selection Notes

Select this component when a combined mixer and frequency synthesizer solution is needed for up-conversion tasks. Consider the 270mA current draw and 4.75V-5.25V supply range for power budgeting. The 32-QFN package requires appropriate surface-mount assembly processes. Evaluate the 14dB noise figure against system sensitivity requirements.

RF Mixers Part Context

This device belongs to Asahi Kasei Microdevices' portfolio of RF and wireless components, specifically targeting applications that require integrated frequency generation and mixing functions. It complements other AKM products like the AK1572, though it features a distinct 4x4 QFN package compared to the 5x5 variant found in similar models.

RF Mixers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require functional equivalents from other manufacturers or redesigning the circuit for available components.
