HMC529LP5E

Overview

The HMC529LP5E is a GaAs MMIC Voltage Controlled Oscillator (VCO) operating in the 12.4 GHz to 13.4 GHz frequency range. It features integrated Fo/2 and Div/4 outputs, with tuning voltages ranging from 2 VDC to 13 VDC. The device requires a supply voltage between 4.75 V and 5.25 V, drawing up to 300 mA. Key performance metrics include -110 dBc/Hz phase noise, 6 MHz/V tuning sensitivity, and 18 dBc second harmonic suppression. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates resonators, negative resistance devices, and varactor diodes on a single GaAs MMIC
• Provides simultaneous fundamental, half-frequency (Fo/2), and divided-by-four (Div/4) outputs
• Utilizes InGaP Heterojunction Bipolar Transistor (HBT) technology for high-performance oscillation

Applications

• General purpose RF signal generation
• Local oscillator sources in communication systems
• Frequency synthesis applications requiring multiple output harmonics

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status and moisture sensitivity levels prior to soldering. Ensure storage conditions meet humidity requirements to prevent package degradation. Validate that the specific LP5E suffix matches design specifications for lead-free processing and packaging format.

Selection Notes

Select this component when a wideband VCO covering 12.4–13.4 GHz is required alongside integrated harmonic outputs. Consider the 300 mA current draw and 5 V supply constraints during power budgeting. Evaluate the -110 dBc/Hz phase noise against system sensitivity requirements. Ensure the QFN-32 package footprint aligns with PCB layout capabilities.
