HMC388LP4

Overview

The HMC388LP4 is a surface-mount Voltage Controlled Oscillator (VCO) with an integrated buffer amplifier, manufactured by Analog Devices Inc. It operates within the frequency range of 3.15 GHz to 3.4 GHz. The device utilizes a 24-VFQFN exposed pad package for mounting. Key electrical specifications include a supply voltage of 3 V, a current consumption of 39 mA, and a tuning voltage range from 0 VDC to 10 VDC. The output power is rated at 4.7 dBm, with a phase noise of -112 dBc/Hz and a tuning sensitivity of 5 MHz/V.

Feature Summary

• Integrated buffer amplifier design for improved signal isolation and drive capability
• Surface-mount construction in a compact QFN package for efficient PCB layout
• Wide tuning voltage range supporting flexible frequency control applications

Applications

• VSAT communication systems
• Wireless local loop infrastructure
• Point-to-point microwave links

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct channels. Confirm the specific suffix (e.g., LP4) matches the required package and pinout. Request recent lot traceability data to ensure compliance with RoHS directives. Validate that the supplier provides original manufacturer packaging to prevent counterfeit risks during high-frequency operation.

Selection Notes

Select this component when a stable RF source is required in the 3.15–3.4 GHz band with low phase noise characteristics. Ensure the system design accommodates the 3 V supply voltage and 39 mA current draw. Verify that the 24-pin QFN footprint aligns with the target PCB thermal and mechanical constraints. Consider the integrated buffer if load isolation is critical for the application stability.

Part Context

This part belongs to the HMC388 series of voltage-controlled oscillators designed for RF and microwave applications. It is distinct from evaluation kits such as the 105706-HMC388LP4, which are tools for testing rather than production components. The series targets industries requiring reliable oscillator performance in compact form factors.
