Quick Answers: What is the ADRF5545ABCPZN?

The ADRF5545ABCPZN is a dual-channel, integrated RF front-end multichip module from Analog Devices, designed for TDD applications from 2.4 GHz to 4.2 GHz. It integrates low-noise amplifiers (LNAs) and power amplifiers (PAs) in a compact 40-lead LFCSP-VQ (6x6 mm) package, supporting 2x2 MIMO. Key verified specs: frequency range 2.4-4.2 GHz, dual channels, surface-mount package. As of 2026-08-25, it is active with 99,999 units in stock at XAIPART, priced at $16.19 for 1000+ units. This makes it a strong choice for 5G NR TDD base stations, small cells, and point-to-point links.

Technical Guide: How to Select and Design In the ADRF5545ABCPZN

When selecting the ADRF5545ABCPZN, verify that your system operates within the 2.4-4.2 GHz range and requires dual-channel TDD operation. The module integrates LNA and PA, reducing external component count. For design-in, pay attention to PCB layout: minimize parasitic inductance, provide solid grounding, and solder the exposed pad to a thermal via array for heat dissipation. The TDD_SW pin (pin 8) must be synchronized with system timing to prevent TX/RX leakage. Use the pinout table below for critical connections.
