HMC534LP5

Overview

The HMC534LP5 is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC Voltage Controlled Oscillator (VCO) manufactured by Analog Devices Inc. It operates within a frequency range of 10.6 GHz to 11.8 GHz and provides dual outputs: the fundamental frequency (Fo) and a divided-by-2 output (Fo/2). The device integrates resonators, negative resistance devices, and varactor diodes, eliminating the need for external resonators. Key electrical specifications include an output power of +11 dBm at Fo, typical phase noise of -110 dBc/Hz at 100 kHz offset, and a tuning sensitivity of 20 MHz/V. It requires a supply voltage between 4.75 V and 5.25 V with a current rating of 380 mA.

Feature Summary

• Integrates resonators, negative resistance devices, and varactor diodes on a single MMIC die
• Provides simultaneous fundamental frequency and half-frequency outputs
• Eliminates requirement for external resonator components
• Utilizes GaAs InGaP HBT technology for low phase noise performance

Applications

• Low noise MMIC VCO systems requiring half frequency and divide-by-4 outputs
• Test equipment and industrial controls
• SATCOM applications
• Military end-use systems

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required package variant, as functional differences may exist between suffixes. Ensure compliance with RoHS directives if applicable to the specific revision. Request official datasheets and test reports to validate performance parameters against application requirements before finalizing procurement decisions.

Selection Notes

Select the HMC534LP5 when a compact solution is needed for frequencies between 10.6 GHz and 11.8 GHz with integrated harmonic outputs. Consider the 380 mA current consumption and 5 V supply requirement for power budgeting. Evaluate the -110 dBc/Hz phase noise specification against system jitter requirements. Ensure the design accommodates the 32-lead QFN package dimensions and thermal management needs associated with the MMIC structure.

Part Context

The HMC534LP5 belongs to the HMC series of monolithic microwave integrated circuits from Analog Devices. This series focuses on providing complete RF solutions in small form factors. The LP5 suffix typically denotes a specific lead-free package configuration. Related models in the family often share similar integration levels but vary in frequency ranges and output configurations.
