HMC509LP5TR

Overview

The HMC509LP5TR is a Voltage Controlled Oscillator (VCO) manufactured by Analog Devices Inc., utilizing GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC technology. It operates in two distinct frequency bands: 3.9 to 4.4 GHz and 7.8 to 8.8 GHz, with center frequencies of 4.15 GHz and 8.3 GHz respectively. The device features a tuning voltage range of 2 VDC to 13 VDC and requires a supply voltage of 5 V. Key electrical specifications include a typical phase noise of -115 dBc/Hz, a push of 10 MHz/V, and a second harmonic level of 10 dBc. It draws a maximum current of 270 mA and is housed in a 32-VFQFN exposed pad package.

Feature Summary

• Integrates GaAs InGaP HBT MMIC technology for dual-band operation
• Provides Fo/2 output capability alongside fundamental frequency generation
• Features low phase noise performance suitable for high-frequency applications
• Operates within a wide tuning voltage range for flexible frequency control

Applications

• Wireless communication systems requiring stable local oscillators
• Test and measurement equipment needing precise frequency synthesis
• Satellite communication transceivers operating in Ku-band frequencies

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing components. Confirm that the part status aligns with project requirements, as availability may be restricted or limited. Ensure compatibility with the required 32-VFQFN footprint and soldering profiles during assembly planning. Cross-reference datasheet revisions to confirm parameter consistency for production validation.

Selection Notes

Select this component when dual-band VCO functionality is required within a single compact surface-mount package. Consider the 270 mA current draw for power budget calculations and thermal management strategies. Evaluate the -115 dBc/Hz phase noise against system sensitivity requirements. Verify that the 2 V to 13 V tuning voltage range matches the available control circuitry in the design.
