AD831APZ

Product Overview

AD831APZ from Analog Devices Inc. is a wideband active RF 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: AD831APZ
• Device Type: wideband active RF mixer
• Mixer Configuration / Topology: High performance active mixer with wideband RF, LO and IF ports
• RF Frequency Range: Broadband operation from dc / low IF region to about 500 MHz class applications
• LO Frequency Range / Drive: Wideband LO input suitable for high dynamic range frequency conversion
• IF Frequency Range: Broadband IF output for transmit or receive frequency conversion
• Conversion Gain / Loss: Approximately 0 dB to several dB conversion gain depending on port matching and operating frequency
• Linearity / P1dB: High linearity active mixer architecture for demanding receiver/transmitter paths
• Noise Figure / Receiver Noise: Noise performance depends on operating frequency and biasing; intended for low distortion mixer use
• Supply / Bias: Single 5 V class analog supply operation
• Package / Case: 20-lead PLCC / APZ package family
• Operating Temperature: Industrial/commercial grade depending on suffix
• Design Notes: Best suited when wideband active mixing and low external component count are more important than passive mixer loss.

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 mixer suffix, package footprint and frequency plan must remain compatible with the existing RF design.

Quality & Sourcing

Antrex Electronics can support sourcing for AD831APZ 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.
