HMC798LC4TR

Product Overview

HMC798LC4TR from Analog Devices Inc. is a GaAs MMIC subharmonically pumped 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: HMC798LC4TR
• Device Type: GaAs MMIC subharmonically pumped mixer
• Mixer Configuration / Topology: ×2 LO subharmonic mixer with integrated LO amplifier
• RF Frequency Range: 24 GHz to 34 GHz
• LO Frequency Range / Drive: LO amplifier / half-frequency LO pumping architecture for 24 GHz to 34 GHz RF conversion
• IF Frequency Range: Wide IF bandwidth depending on application circuit
• Conversion Gain / Loss: Millimeter-wave conversion loss class, dependent on RF band and LO drive
• Linearity / P1dB: 2×LO to RF isolation typically 30 dB to 36 dB depending on frequency band
• Noise Figure / Receiver Noise: Noise figure depends on conversion-loss region and LO amplifier bias
• Supply / Bias: 5 V dc LO amplifier bias class
• Package / Case: ALC4 leadless LCC package family
• Operating Temperature: -40°C to +85°C class depending on suffix
• Design Notes: Use HMC798 when a 24 GHz to 34 GHz design needs subharmonic LO drive rather than a fundamental LO at RF frequency.

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 HMC798LC4TR 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.
