HMC734LP5E

Overview

The HMC734LP5E is a GaAs InGaP HBT MMIC Voltage Controlled Oscillator (VCO) by Analog Devices Inc. It operates within an output frequency range of 8.6 GHz to 10.2 GHz and includes an integrated divide-by-4 prescaler, providing a secondary output of 2.15 GHz to 2.55 GHz. The device delivers +18 dBm output power with typical phase noise of -100 dBc/Hz at 100 kHz offset. It requires a supply voltage between 4.75 V and 5.25 V, draws 240 mA current, and accepts a tuning voltage from 1 VDC to 13 VDC. The component features a 32-lead QFN package measuring 5x5 mm.

Feature Summary

• Integrates a resonator, negative resistance device, varactor diode, and divide-by-4 frequency output without requiring external resonators.
• Provides dual outputs: a primary high-frequency signal and a divided-down low-frequency signal for direct mixing applications.

Applications

• Point-to-Point/Multi-Point Radio Systems
• SATCOM Applications
• Test Equipment & Industrial Controls

Procurement Notes

Verify the specific suffix 'E' indicates RoHS compliance status as per manufacturer documentation. Confirm availability through authorized distributors, noting that some channels may report limited stock or restricted sales regions. Ensure the ordering part number matches the exact package and pin configuration required for the target PCB layout.

Selection Notes

Select this component when a single-chip solution for high-frequency generation and division is required. The integrated divide-by-4 feature simplifies circuit design by eliminating external dividers. Consider the 240 mA current draw and thermal management requirements associated with the QFN-32 package during system integration.
