Low Noise Amplifiers


This low noise amplifier (LNA) operates in the 80-105 GHz frequency range and features 16 dB linear gain, a 5 dB noise figure from 80 to 90 GHz, a 3.40x1.60x0.07mm chip size, and VD=2.5V @ ID=115 mA DC bias.

The LNA-30-00104000-75-15P from L3 Harris Narda-Miteq is a low noise amplifier (LNA) that operates from 0.1 to 40 GHz. It provides a gain of more than 30 dB with a noise figure of 7.5 dB and a P1dB of over 15 dBm. The amplifier requires a supply of 15 V and consumes up to 500 mA of current.

The Ultra Low Noise, High Linearity Active Bias Low Noise Amplifier: MGA-633P8 is the latest addition to the Avago Technologies family of ultra low noise, high gain, high linearity Gallium Arsenide (GaAs) Active Bias Low Noise Amplifiers (LNA). The device provides Best In Class NF (0.38dB @ 900MHz) performance and is designed to be used as first stage LNA within cellular base station transceiver radio cards, tower mounted amplifiers (TMA), combiners, repeaters and remote/digital radio heads.

Northrop Grumman Microelectronics Products & Services’ latest entry in their series of W-band products include two new InP HEMT low noise amplifiers covering the 71-96 and 80-100 GHz frequency ranges. Both amplifiers are ideal for applications involving W-band imaging, sensors, radar, and short haul/high capacity links.

This low noise amplifier (LNA) is ideal for applications involving radar, short haul/high capacity links, sensors, millimeter-wave imaging RC chains, and other applications where broad bandwidth and good return loss are important.

The Avago MGA-21108 is a fully integrated GaAs Low Noise Amplifier, LNA, MMIC for use in the 1.5GHz to 8GHz band.

The ERZ-LNA-0270-0310-30-0.5 is a low noise amplifier (LNA) from Erzia is designed for applications operating within the 2.7 to 3.1 GHz frequency range. The LNA provides 29 dB of gain with a noise figure of 0.5 dB. Its modularity and compact size make it an optimal choice for a wide range of applications, including industrial, laboratory, satcom, telecom, space, aerospace, and military applications.

RFMD's RFLA1018 is an analog-controlled voltage-variable gain amplifier featuring high linearity and very low noise figure. This LNA with bypass mode and variable attenuator provides over 35dB of dynamic gain range. The RFLA1018 has a 3.3V control range with maximum gain at 0V. The LNA is temperature compensated to reduce gain variation. A noise figure of 0.65dB and an IIP3 of 2dBm make this component ideal for receiver input lineups. The RFLA1018 is packaged in a small 8.0mm x 8.0mm leadless laminate MCM. This module is internally matched to 50Ω on all RF ports, making it easy to use with no external matching components required.
