ADRF5519BCPZN-RL

Product Overview

ADRF5519BCPZN-RL from Analog Devices Inc. is a dual-channel TDD RF receiver front-end module used in RF front-end designs that need integrated transmit, receive, switching or low-noise signal-chain functions. This description focuses on practical RF parameters such as band coverage, PA/LNA path behavior, control requirements and package compatibility.

The exact orderable suffix should be matched before purchase because RF front-end devices often vary by band plan, pinout, reel format, qualification grade and control-state truth table.

Key Features

• Manufacturer: Analog Devices Inc.
• Part Number: ADRF5519BCPZN-RL
• Device Type: dual-channel TDD RF receiver front-end module
• RF Band / Frequency Range: 1.8 GHz to 2.8 GHz
• Transmit / PA Path: Integrated high-power SPDT switch for TDD transmit/receive routing
• Receive / LNA Path: Dual receive channels with cascaded LNA stages, high-gain/low-gain control and low noise figure for cellular-band receiver paths
• Output Power / Linearity: Designed for high-power TDD infrastructure receive protection and receive-chain switching
• Control / Bias: 5 V supply family with positive logic control, LNA gain states and power-down mode
• System Impedance: 50 Ω RF interface where specified by the device reference design or data sheet
• Package / Case: 6 mm x 6 mm, 40-lead LFCSP package
• Operating Temperature: RF front-end module temperature range is suffix-specific; verify industrial or automotive grade before sourcing
• Design Notes: Confirm whether ADRF5519 frequency range and power-handling limits match the target LTE/5G band plan.

Applications

TDD cellular infrastructure, 4G/5G small cells, receive diversity paths and remote-radio unit front ends.

Also suitable for engineering replacements, shortage support and BOM consolidation where the same RF band, package footprint and control interface must be maintained.

Quality & Sourcing

Antrex Electronics can support sourcing for ADRF5519BCPZN-RL through available stock checks, BOM consolidation and alternative-lot review. For RF front-end modules, packaging condition, date code, MSL handling, reel labeling and moisture exposure should be checked before shipment.

For project builds, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers reduce risk when sourcing hard-to-find or lifecycle-sensitive RF front-end components.
