I. Introduction to ADI GaAs pHEMT Low-Noise Amplifiers

ADI boasts an extensive product portfolio in the RF and microwave sectors. Its GaAs pHEMT low-noise amplifiers are based on gallium arsenide pseudomorphic high-electron-mobility transistor (pHEMT) technology and feature a low noise figure, high gain, wide bandwidth and high linearity, making them suitable for receiver front-ends where high system sensitivity is required.

GaAs pHEMT low-noise amplifiers are typically used to amplify weak RF signals whilst minimising their own noise contribution, thereby enhancing the overall reception sensitivity of the equipment. ADI’s relevant products cover multiple frequency bands and package types, commonly including the HMC series, such as the HMC565, HMC566, HMC717, HMC752 and HMC753.

II. Key Technical Features

ADI GaAs pHEMT low-noise amplifiers typically offer the following technical advantages:

Low noise figure: helps improve receiver sensitivity and signal-to-noise ratio;

High gain: reduces the impact of noise from subsequent stages;

Wide bandwidth coverage: supports a wide range of applications from low frequencies to the millimetre-wave band;

High linearity: certain models feature a high OIP3, making them suitable for complex modulated signals;

50 Ω matching: facilitates integration into RF systems;

Multiple power supply options: certain models support single-supply or dual-supply operation;

Various package types: including bare die and SMT packages, to accommodate different integration requirements;

GaAs pHEMT process: suitable for high-frequency, low-noise and high-reliability applications.

III. Overview of Key Models

1. ADL5523: 400 MHz to 4 GHz GaAs pHEMT LNA, widely used in S-band receivers; featuring low noise and high gain, it is a commonly used model in wireless communications and radar intermediate frequency receivers.

2. ADL8107: 6 GHz to 18 GHz broadband low-noise amplifier, with a typical noise figure of 1.3 dB and typical gain of 24 dB from 7 GHz to 16 GHz; high OIP3 linearity; built-in 50 Ω matching; compact 2 mm × 2 mm LFCSP package, suitable for high-density SMT RF board designs.

3. HMC8410: A broadband LNA operating from 0.01 GHz to 10 GHz, with a typical noise figure as low as 1.1 dB, small-signal gain of 19.5 dB, OIP3 up to 33 dBm and high dynamic range, suitable for test equipment and broadband receivers.

4. HMC8401-DIE: DC to 28 GHz GaAs pHEMT die, with a gain of 14.5 dB and a figure of noise of 1.5 dB; supports die-bonding integration; designed for VSAT satellite communications and microwave radio applications.

5. ADL8106: 20 GHz–54 GHz millimetre-wave GaAs pHEMT low-noise amplifier, covering the K and Ka bands, suitable for millimetre-wave communications and radar front-end reception.

6. HMC1126ACEZ: 400 MHz–52 GHz ultra-wideband LNA, integrating DC-blocking and decoupling passive components; requires no additional external components, simplifying high-frequency board design.
