AD8345AREZ

Product Overview

AD8345AREZ from Analog Devices Inc. is a 140 MHz to 1000 MHz quadrature modulator. This product detail focuses on the RF modulation architecture, operating band, baseband interface, linearity and package considerations for engineering and sourcing teams.

The device is relevant for transmitter signal chains where complex I/Q modulation, vector modulation, phase modulation or modulator-driver functionality must match the original BOM and board-level RF design.

Applications

Wireless infrastructure, microwave radio, broadband access, satellite modem, instrumentation and complex-modulation transmitter designs.

Replacement builds, shortage support and BOM sourcing projects where RF range, baseband interface, package and supply requirements must remain compatible.

Quality & Sourcing

Antrex Electronics can support sourcing for AD8345AREZ through available stock checks, BOM consolidation and alternative-lot review. For RF modulator ICs, packaging condition, date code, MSL handling and original labeling should be checked before shipment.

For project builds or shortage support, Antrex Electronics can coordinate visual inspection, package verification and third-party electrical or authenticity testing when required. This helps buyers manage risk when sourcing discontinued, allocated or hard-to-find RF modulator parts.
