HMC509LP5

Overview

The HMC509LP5 is a GaAs InGaP HBT MMIC Voltage Controlled Oscillator operating from 7.8 to 8.8 GHz with a half-frequency output of 3.9 to 4.4 GHz. It delivers +12.5 dBm output power and achieves -115 dBc/Hz phase noise at 100 kHz offset. The device requires no external resonators or matching components, utilizing a leadless QFN-32 package measuring 5x5 mm. Control voltage ranges from 2 V to 13 V, with a tuning sensitivity of 10 MHz/V. Maximum current consumption is 270 mA, and it operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• Dual output capability providing fundamental frequency (Fo) and half-frequency (Fo/2) signals without external resonators
• Integrated GaAs InGaP HBT MMIC design eliminating the need for external matching components
• Leadless QFN surface mount package facilitating compact PCB layout

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. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate tape-and-reel packaging versus cut tape options. Ensure supply chain documentation matches the exact part number variant required for your manufacturing process.

Selection Notes

Select this component when dual-frequency generation is required in a minimal footprint. The integrated design simplifies circuit architecture by removing passive resonator requirements. Consider the 270 mA current draw and thermal management needs associated with the 5x5 mm package dimensions during system design.

Part Context
