HMC388LP4ETR

Overview

The HMC388LP4ETR 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 and is housed in a 24-lead QFN package measuring 4 mm x 4 mm x 1 mm. The device requires a supply voltage between 2.75 V and 3.25 V, drawing approximately 40 mA of current. It features a tuning voltage range of 0 VDC to 10 VDC and delivers an output power of 5 dBm. The component supports operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates a VCO core with a dedicated buffer amplifier for signal isolation
• Designed specifically for VSAT communication applications
• Utilizes BiCMOS technology for high-frequency performance

Applications

• VSAT satellite communication systems
• Microwave radio links
• Point-to-point wireless transmission equipment

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Analog Devices Inc., as manufacturing sources may vary. Confirm that the 24-QFN package dimensions align with your PCB footprint requirements. Ensure that the supply voltage and tuning voltage ranges are compatible with your system's power management and control circuitry before finalizing procurement.

Selection Notes

Select this component when a compact, low-power VCO solution is required for C-band or Ku-band VSAT applications. The integrated buffer simplifies design by reducing the need for external amplification stages. Consider the thermal dissipation capabilities of the exposed pad QFN package if operating at maximum temperature limits. Verify that the phase noise specifications meet the strict requirements of your modulation scheme.

Part Context

This part belongs to the HMC388 series of RF MMICs from Analog Devices Inc. It is functionally related to other components in the HMC family designed for microwave frequencies. The LP4 suffix indicates the specific leadless package type used for surface mount assembly. It serves as a key frequency generation element in upconversion or downconversion chains for satellite ground stations.
