HMC156AC8

Overview

The HMC156AC8 is a passive surface-mount frequency doubler designed for DBS and VSAT applications. It operates within an input frequency range of 700 MHz to 2.4 GHz, producing doubled output frequencies between 1.6 GHz and 3.4 GHz. The device utilizes a non-hermetic ceramic 8-SOIC package (0.154 inch width). It maintains a standard 50 Ohm impedance and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Passive surface-mount design suitable for compact RF circuits
• Effective suppression of undesired fundamental and higher-order harmonics
• Non-hermetic ceramic construction for robust performance

Applications

• Direct Broadcast Satellite (DBS) systems
• Very Small Aperture Terminal (VSAT) communications
• RF signal chain frequency conversion stages

Procurement Notes

Verify the current lifecycle status before procurement, as sources indicate this component may be obsolete or discontinued. Confirm availability through authorized distributors, noting that standard packaging quantities may apply. Ensure the specific AC8 suffix matches the required 8-SOIC ceramic package variant for your design integration.

Selection Notes

Select this component when a passive frequency doubling solution is required for C-band or Ku-band uplink/downlink paths. The 8-SOIC package facilitates automated surface-mount assembly. Verify that the input power levels remain within the safe operating area for passive doublers to prevent damage, and ensure the 50 Ohm system impedance aligns with surrounding circuitry.

Part Context

This part belongs to the HMC series of RF integrated circuits manufactured by Analog Devices Inc., formerly Hittite Microwave Corporation. The series includes various amplifiers, mixers, and doublers targeting satellite and wireless infrastructure markets. The HMC156 specifically addresses frequency multiplication needs in consumer and professional satellite reception equipment.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the potentially obsolete status, engineers should consult official manufacturer channels for recommended alternatives or redesign considerations using active components from the same family.
