HMC555

Product Overview

HMC555 from Analog Devices Inc. is a GaAs MMIC double-balanced mixer used for RF and microwave frequency conversion. This product detail focuses on practical mixer parameters such as RF/LO/IF range, conversion performance, linearity, drive requirements and package compatibility.

The device is suitable for receiver, transmitter, upconversion or downconversion stages where the exact suffix must be matched for package, tape-and-reel format, temperature grade and RF layout before purchase.

Key Features

• Manufacturer: Analog Devices Inc.
• Part Number: HMC555
• Device Type: GaAs MMIC double-balanced mixer
• Mixer Configuration / Topology: Passive double-balanced mixer for microwave up/downconversion
• RF Frequency Range: 1.7 GHz to 3.5 GHz class RF/LO coverage
• LO Frequency Range / Drive: External LO drive class around +13 dBm to +15 dBm
• IF Frequency Range: Broad IF bandwidth depending on external matching
• Conversion Gain / Loss: Low conversion loss passive mixer class
• Linearity / P1dB: High dynamic range passive mixer behavior depends on LO drive and IF match
• Noise Figure / Receiver Noise: Passive mixer noise figure approximately follows conversion loss
• Supply / Bias: Passive device, no dc bias required
• Package / Case: Die or microwave package option depending on suffix
• Operating Temperature: -40°C to +85°C class depending on suffix
• Design Notes: Use exact HMC555 suffix only when the original design uses the same RF/LO/IF transitions and LO level.

Applications

Wireless infrastructure, cellular base stations, microwave radios, satellite communication equipment, radar front ends, test instruments and broadband receiver or transmitter conversion paths.

Repair, prototype and shortage-support builds where original Analog Devices / Hittite / Maxim mixer suffix, package footprint and frequency plan must remain compatible with the existing RF design.

Quality & Sourcing

Antrex Electronics can support sourcing for HMC555 through available stock checks, BOM consolidation and alternative-lot review. For RF mixer components, date code, MSL handling, original label condition and package integrity should be reviewed before shipment.

For production recovery, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers manage risk when sourcing discontinued, legacy or hard-to-find RF mixer parts.
