HMC508LP5

Overview

The HMC508LP5 is a GaAs InGaP HBT MMIC Voltage Controlled Oscillator (VCO) operating from 7.3 to 8.2 GHz with a half-frequency output of 3.65 to 4.1 GHz. It delivers +15 dBm typical output power at +5V supply and achieves -116 dBc/Hz phase noise at 100 kHz offset. The device integrates resonators, negative resistance devices, and varactors within a leadless QFN 5x5 mm SMT package, eliminating the need for external matching components or resonators.

Feature Summary

• Dual-output architecture providing fundamental frequency and half-frequency signals on a single chip
• Integrated passive components eliminate requirement for external resonators or matching networks
• Robust phase noise performance maintained across temperature, shock, and process variations

Applications

• VSAT radio systems
• Point-to-point and multi-point radio links
• Test equipment and industrial controls
• Military end-use applications

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the received part matches the specific HMC508LP5 designation and packaging type. Ensure storage and handling procedures comply with ESD protection standards for sensitive MMIC devices. Review the official datasheet for detailed electrical specifications and thermal management requirements before integration into final designs.

Selection Notes

Select this VCO when dual-frequency generation is required without additional circuitry. The integrated design reduces board space and simplifies layout by removing external resonator dependencies. Consider the +5V supply requirement and current consumption limits during system power planning. Evaluate the phase noise specification against system sensitivity requirements for communication or test applications.

Part Context

This component belongs to the Hittite Microwave (now Analog Devices) family of low-noise MMIC voltage controlled oscillators. These devices utilize GaAs InGaP Heterojunction Bipolar Transistor technology to achieve high performance in compact packages. The series is designed for applications requiring stable frequency generation with minimal external support components.
