Analog Devices Inc./Maxim Integrated MAX2614ETA/V+T

Overview

MAX2614ETA/V+T from Maxim Integrated is a high-performance broadband RF gain block designed as a low-noise amplifier or cascadable 50Ω amplifier for cellular infrastructure and microwave radio systems. It delivers +13.6dBm output P1dB at 1GHz, 18.6dB gain, 2.0dB noise figure at 2GHz, and operates from 40MHz to 4000MHz on a +3V to +5.25V supply.

For engineers reviewing the MAX2614ETA/V+T datasheet, MAX2614ETA/V+T pinout, MAX2614ETA/V+T application, or MAX2614ETA/V+T equivalent, key selection criteria include its AEC-Q100 qualification, shutdown mode capability, 2mm × 3mm TDFN package, and verified OIP3 of +29.7dBm at 1GHz with dual-tone input.

Technical Context

The MAX2614ETA/V+T uses a rugged bipolar process with Darlington architecture, enabling industry-leading +20dBm maximum input power handling without external protection circuitry. Its internally matched 50Ω input and output simplify integration into wideband RF signal chains.

It features an enable/disable control (EN/RBIAS pin) for power management in battery-sensitive or burst-mode applications, with shutdown supply current of 7µA. Thermal performance is optimized via exposed-pad TDFN packaging with θ_JA = 60°C/W on four-layer PCBs.

Key Specifications

Pinout & Package

FAQ

What is the operating temperature range for MAX2614ETA/V+T?

The MAX2614ETA/V+T is rated for operation from -40°C to +85°C and is AEC-Q100 qualified for automotive use. This range is guaranteed across all electrical specifications including gain, noise figure, and OIP3. The junction temperature limit is +150°C, and thermal resistance (θ_JA) is 60°C/W on a four-layer PCB. MAX2614ETA/V+T maintains stable performance across this full range without derating in typical RF board layouts.

Does MAX2614ETA/V+T support shutdown mode, and how is it controlled?

Yes, MAX2614ETA/V+T supports shutdown mode via the EN/RBIAS pin (Pin 4). Applying a logic-low signal disables the amplifier and reduces supply current to 7µA. Leaving the pin unconnected enables normal operation. The control interface is designed for compatibility with open-collector or high-Z logic outputs, and MAX2614ETA/V+T's shutdown behavior is fully characterized across temperature and supply voltage variations.

What are the decoupling requirements for MAX2614ETA/V+T's VCC pin?

MAX2614ETA/V+T requires three-tier decoupling on the VCC pin (Pin 5): a 470pF ceramic capacitor and a 10nF ceramic capacitor placed as close as possible to the pin, plus a 10µF tantalum bulk capacitor with ESR > 2Ω located nearby. This configuration suppresses supply noise across RF, switching, and low-frequency bands. Failure to implement all three elements may degrade MAX2614ETA/V+T's OIP3 and gain flatness, especially above 2GHz.

Is MAX2614ETA/V+T pin-compatible with other devices in the MAX2612–MAX2616 family?

Yes, MAX2614ETA/V+T shares identical pinout, package (8-pin TDFN-EP), and footprint with MAX2612ETA+, MAX2613ETA+, MAX2615ETA+, MAX2615ETA/V+, and MAX2616ETA+. All family members use the same RFIN, RFOUT, VCC, EN/RBIAS, GND, and EP connections. This enables drop-in replacement during prototyping or design iteration-though electrical parameters like OIP3, P1dB, and bias current differ per variant, so system-level validation is required after substitution.

What is the maximum RF input power rating for MAX2614ETA/V+T?

The absolute maximum RF input power rating for MAX2614ETA/V+T is +20dBm, enabled by its rugged bipolar Darlington architecture. This rating applies across the full 40MHz–4000MHz frequency range and is not conditional on temperature or supply voltage. The +20dBm tolerance reduces or eliminates the need for external limiter or attenuator circuits in front-end designs, simplifying MAX2614ETA/V+T integration in high-dynamic-range receivers and shared-antenna systems.
