HMC365S8G

Overview

The HMC365S8G is a low-noise divide-by-4 static frequency divider utilizing InGaP GaAs HBT technology. It operates from DC to 13 GHz input frequency with a single +5V supply. The device features an additive SSB phase noise of -151 dBc/Hz at 10 MHz offset. It is housed in an 8-lead surface mount plastic package (SOP8). Key electrical parameters include a minimum operating voltage of 4.75 V and maximum of 5.25 V, with a typical operating current of 110 mA. Output power is specified at 5 dBm.

Feature Summary

• Implements divide-by-4 frequency division using InGaP GaAs HBT technology for high-speed performance.
• Provides low additive SSB phase noise characteristics suitable for precision signal processing.
• Operates on a single +5V DC power supply, simplifying integration into existing RF systems.

Applications

• VSAT communication systems requiring precise frequency control
• High-speed data transmission modules
• RF signal chain frequency synthesis

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix designation matches project requirements, as packaging variants exist. Check current availability status, as supply constraints may affect lead times. Ensure ESD handling protocols are followed due to moisture sensitivity and semiconductor nature. Validate that the SOP8 package fits the target PCB footprint before ordering.

Selection Notes

Select this component when a divide-by-4 ratio is required up to 13 GHz input frequencies. Consider the InGaP GaAs HBT process for superior high-frequency performance compared to standard CMOS alternatives. Evaluate the -151 dBc/Hz phase noise specification against system jitter requirements. Ensure the design accommodates the 110 mA current draw and +5V supply constraint. Verify thermal management capabilities for the surface-mount package in the intended environment.

Part Context

The HMC365S8G belongs to the HMC365 series of prescalers and dividers from Analog Devices. It complements other family members like the HMC365S8GETR (tape and reel) and bare die versions. This series targets wireless and RF integrated circuit applications, providing reliable frequency division solutions across the DC to 13 GHz spectrum for professional communications infrastructure.

Replacement Considerations

Direct substitutes include the HMC365S8GETR for tape-and-reel packaging needs. For different division ratios within the same technology, consider HMC361S8GE (divide-by-2) or HMC363G8 (divide-by-8). Verify pin compatibility and electrical specifications before swapping with other Analog Devices RF ICs.
