MAX2678GTB/V+

Product Overview

MAX2678GTB/V+ from Analog Devices / Maxim Integrated is a GPS/GNSS LNA front-end IC 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 / Maxim Integrated
• Part Number: MAX2678GTB/V+
• Device Type: GPS/GNSS LNA front-end IC
• RF Band / Frequency Range: GPS L1 / GNSS 1575 MHz class receiver front-end band
• Transmit / PA Path: Receive-only front-end device; not a PA/FEM transmit module
• Receive / LNA Path: Integrated GPS LNA path used ahead of GNSS receiver ICs to improve sensitivity and link margin
• Output Power / Linearity: Low-power receiver front-end class for battery or automotive GNSS modules
• Control / Bias: Low-voltage supply and enable/shutdown control depending on suffix
• System Impedance: 50 Ω RF interface where specified by the device reference design or data sheet
• Package / Case: TDFN/TQFN-class small RF package
• Operating Temperature: RF front-end module temperature range is suffix-specific; verify industrial or automotive grade before sourcing
• Design Notes: Check automotive qualification suffix, external SAW/filter placement and LNA bias mode for the target design.

Applications

GNSS receiver modules, active GPS antenna circuits, telematics units and navigation receivers.

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 MAX2678GTB/V+ 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.
