HMC611-SX

Overview

The HMC611-SX is a broadband logarithmic RF power detector and controller manufactured by Analog Devices Inc. It operates within a frequency range of 0.001 GHz to 10 GHz, providing a dynamic range of up to 70 dB with a measurement accuracy of ±1 dB over a 51–54 dB span at frequencies up to 8 GHz. The device features a nominal log slope of -25 mV/dB and supports both detector and controller modes for automatic gain or power control applications. It integrates a buffered temperature sensor and requires a 5 V supply voltage.

Feature Summary

• Supports dual operation as a logarithmic detector or an automatic gain/power controller
• Integrates a buffered temperature sensor for thermal monitoring
• Provides high-precision signal detection across a wide bandwidth

Applications

• Wireless infrastructure systems
• Radar systems
• Receiver signal strength indication (RSSI)
• Power monitoring and control circuits

Procurement Notes

Verify the obsolete status of the HMC611-SX before procurement planning. Confirm availability through authorized distributors or secondary market suppliers like Rochester Electronics. Ensure that any substitute components meet the original electrical specifications and pinout requirements for seamless integration into existing designs.

Selection Notes

Select this component for applications requiring wideband logarithmic detection up to 10 GHz. Consider the integrated temperature sensor for environments requiring thermal compensation. Evaluate the need for controller functionality if automatic gain or power regulation is required in the signal chain.

Part Context

The HMC611-SX belongs to the HMC611 series of RF detectors. The '-SX' suffix typically denotes a die or specific package variant intended for surface mount or custom integration. This part is part of Analog Devices' portfolio of wireless and RF integrated circuits designed for high-performance communication systems.

Replacement Considerations

Public confirmed substitutes include AD8317ACPZ-R7. Verify compatibility regarding frequency range, dynamic range, and interface requirements when transitioning from the obsolete HMC611-SX.
