Low Noise Amplifiers


A low noise amplifier is primarily used to amplify signals that have been captured by an antenna and are too weak to read making them unreliable when used in electronic communication systems. Because they are used in conjunction with antennas, a low noise amplifier will typically need to be mounted close to the antenna to minimize losses in the feed line.

Ducommun offers the AFB-E27HP-01 ultra-broadband, low-noise power amplifier (LNPA) that covers the millimeter-wave E-band (60 – 90 GHz) for applications such as research, telecommunications, astronomy, remote sensing and imaging, and test and medical instrumentation.

Teledyne Microwave Solutions (TMS) offers a wide range of RF modules specifically designed to meet demanding small size, weight, power and cost (SWaP-C) applications in the Land, Air and Marine markets. Using unique chip and wire capabilities TMS offers extremely rugged and reliable products suitable for the most demanding platforms.

Skyworks offers the SKYH22001 ultra-broadband hermetically sealed low-noise amplifier with superior gain flatness and exceptional linearity. Ideal applications include L and S band communications, radar and weather satellites, test and measurement, extreme industrial and medical equipment, as well as aerospace and defense applications.

This low noise amplifier (LNA) features a small size and low power consumption, making it ideal for point to point/multipoint radios, military and space communications, and other EW and communications systems.

The SKYA21043 is a highly integrated, 5 GHz front-end module (FEM) designed specifically for 802.11p V2V and V2X applications. The module incorporates a 5 GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch, a 5 GHz high-gain low-noise amplifier (LNA) with bypass, and a 5 GHz power amplifier (PA) intended for high-power 802.11p applications and systems.

The MwT-0618S-H5G2 and the MwT-0618Z-H5G2 are low noise, high gain open-carrier amplifier modules operating between 6 and 18 GHz. Their input and output ports are matched to 50 O impedance.

This low noise amplifier (LNA) operates in the 1.5-2.7 GHz frequency range, and is ideal for 3G/4G base station transceivers and repeaters, TDD/FDD systems, defense, and other wireless applications.
