HMC8364LP6GE

Overview

The HMC8364LP6GE is a GaAs MMIC quadband voltage-controlled oscillator (VCO) from Analog Devices. It operates in the 18.10 GHz to 26.60 GHz range, covering four distinct bands: 18.2–20.5 GHz, 20.7–23.0 GHz, 23.2–25.5 GHz, and 25.7–26.5 GHz. The device utilizes a dual-ring topology for low phase noise performance. It features an integrated varactor and tuning circuitry, requiring a single DC supply voltage. The component is housed in a QFN-40 package suitable for surface mount applications.

Procurement Notes

Verify the specific band configuration required for the application, as the quadband nature necessitates appropriate tuning voltage ranges. Confirm RoHS compliance status through official documentation prior to procurement. Ensure the design accounts for the thermal characteristics of the GaAs substrate and the QFN-40 package footprint. Cross-reference the latest datasheet revision to confirm pinout and electrical specifications match the intended implementation.

Selection Notes

Select this component when high-frequency coverage between 18 GHz and 26.6 GHz is required with minimal external passive components. The integrated design reduces board space compared to discrete solutions. Consider the phase noise requirements at various offset frequencies relative to the carrier. Evaluate the power consumption against system thermal limits. The quadband capability allows for flexible frequency planning within the specified range without changing hardware.
