Low Noise Amplifiers


Qorvo offers the new QPB9337 highly integrated front-end module with operation in the 2.8 – 3.8 GHz frequency range for TDD base station, wireless infrastructure, small cell BTS, and pre-5G/5G massive MIMO applications. This LNA module integrates a two-stage LNA and a high-power switch in a dual-channel configuration.

The HLNA Series of Low Noise Amplifiers covers the frequency range from 14 to 110 GHz. A wide variety of gain and bandwidth combinations are available to provide solutions for radar systems, communications systems and other applications. Variations of the amplifiers listed in the HLNA data sheet and totally new amplifier designs can also be provided, usually without an NRE charge. Most models offer single bias operation with internal regulation and bias sequencing. MMIC technology is employed in every amplifier for high reliability and repeatability.

Qorvo offers a front end module (FEM) and two low noise amplifiers (LNAs) designed specifically for Wi-Fi applications such as access points and wireless routers.

The HILNA™ HF is a low noise amplifier (LNA) featuring high linearity, a wide dynamic range, high intercept, reverse voltage protection, a wide operational voltage range, internal bandpass filtering, low noise, high gain, an internal regulator/active bias, high reliability, multi-octave frequency coverage, a ruggedized assembly, and more.

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 TQL9092 from Qorvo is a flat-gain, high-linearity, ultra-low-noise amplifier (LNA) optimized for the 0.6 – 4.2 GHz frequency range, but can operate as low as 600 MHz. This LNA provides a gain flatness of 2 dB over a bandwidth range of 1.5 to 3.6 GHz, and can be biased from a positive supply that ranges from 3.3 to 5 volts.

NIC introduces its Wideband LNA designed for C Band, Radar and Satcom applications. This amplifier operates in the frequency range of 4 GHz – 5 GHz, providing high gain, low Noise Figure and is built in an extremely small package size of 1.2 x 0.9 x 0.4 in. Features:1) High Gain- 23dB typ; 2) Low Noise Figure- 0.9dB typ;3) Custom designs available

The HLNAV-364 low-noise amplifier from HXI covers the frequency range from 50 to 65 GHz minimum and is usable over a wider range. The unit offers a minimum of 25 dB of gain over that range.
