HMC538LP4E

Product Overview

HMC538LP4E from Analog Devices Inc. is an analog voltage-controlled RF phase shifter used in RF, microwave or high-speed signal-chain designs. This description focuses on practical electrical parameters, interface requirements and sourcing relevance for engineering and procurement teams.

The exact ordering suffix should be checked for package style, reel or tray format, temperature grade and board-level compatibility before replacing an existing design.

Key Features

• Manufacturer: Analog Devices Inc.
• Part Number: HMC538LP4E
• Device Type: analog voltage-controlled RF phase shifter
• Functional Role: continuous phase adjustment and beamforming phase trim in microwave signal paths
• Function: analog phase shifter controlled by 0 V to +5 V tuning voltage
• Frequency Range: 6 GHz to 15 GHz operating class
• Phase Range: 0 to 800 degrees at 6 GHz and 0 to 450 degrees at 16 GHz typical capability
• Control Bandwidth: about 50 MHz modulation bandwidth on the control port
• Insertion Loss Behavior: designed for consistent insertion loss versus phase shift
• Package / Case: 24-lead 4 mm x 4 mm LP4 / QFN surface-mount package family
• Design Note: check control-voltage linearity, phase range and calibration table in the target beamforming path
• Design Notes: Confirm the exact suffix, package drawing, temperature grade, RF evaluation layout and bias/control sequence before substitution or production approval.

Applications

Phase adjustment, beamforming, test instrumentation, microwave radios and phase-cancellation signal paths.

Replacement builds where the analog control behavior and QFN footprint must remain compatible with the original calibration.

Quality & Sourcing

Antrex Electronics can support sourcing for HMC538LP4E through available stock checks, BOM consolidation and alternative-lot review. For RF and microwave ICs, package markings, moisture sensitivity, date code and original labeling should be checked before shipment.

For shortage coverage, repair builds or production support, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers reduce risk when sourcing discontinued, legacy or hard-to-find RF miscellaneous ICs and modules.
