HMC735LP5ETR

Overview

The HMC735LP5ETR is a GaAs InGaP HBT MMIC Voltage Controlled Oscillator (VCO) in a 5x5 mm QFN-32 package. It operates from 10.5 to 12.2 GHz with +17 dBm output power and -100 dBc/Hz phase noise at 100 kHz offset. A divide-by-4 output provides 2.625 to 3.05 GHz. It requires no external resonators or matching components, runs on a +5V supply, and supports tuning voltages of 1 VDC to 13 VDC.

Feature Summary

• Integrates resonators, negative resistance devices, and varactor diodes for monolithic stability
• Provides dual outputs including fundamental frequency and divided-by-four signal
• Eliminates need for external resonators or matching components
• Prescaler function can be disabled to conserve current when not required

Applications

• Point-to-Point/Multi-Point Radio systems
• Test Equipment & Industrial Controls
• SATCOM applications
• Military End-Use

Procurement Notes

Verify the specific suffix 'ETR' indicates tape-and-reel packaging versus the 'E' variant which may be cut-tape. Confirm RoHS compliance status as datasheets indicate non-compliance for some variants. Ensure the supplier provides the official Analog Devices datasheet for the exact revision. Check lead times due to limited availability status reported by distributors.

Selection Notes

Select this component when a high-power VCO with an integrated low-frequency output is required. The divide-by-4 feature simplifies synthesizer design by providing a reference signal directly. Consider the +17 dBm output power for driving subsequent stages without additional amplification. Verify thermal management requirements for the QFN-32 package in the final application.

Part Context

This part belongs to the HMC735 series of MMIC VCOs from Analog Devices. It utilizes GaAs InGaP HBT technology for robust performance across temperature and process variations. The family is designed for high integration, reducing board space and component count compared to discrete oscillator solutions.

Replacement Considerations

HMC735LP5E is the same device in cut-tape packaging instead of reel. No direct functional substitutes are confirmed in public documentation.
