Low Noise Amplifiers


This two-stage low noise amplifier (LNA) covers the 7 GHz to 11 GHz frequency range and is 1.5 mm x 1 mm x 0.05 mm. It features a 1dB noise figure at 9 GHz, 23dB small signal gain, and a P1dB output power of 15.5dBm under self-biased condition.

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 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.

Skyworks offers the SKY65903-11 front-end module (FEM) with an integrated low-noise amplifier (LNA) and pre- and post-filters that is ideal for GPS/GNSS/BDS receiver applications. The LNA uses surface-mount technology (SMT) in the form of a 2.5 x 2.5 mm Multi-Chip Module (MCM) package, which allows for a highly manufacturable and low-cost module solution.

Avago presents four low-noise amplifiers (LNAs) to extend the RF performance and diversity of its market-leading LNA portfolio. The new modules feature high linearity that improves an application’s ability to distinguish between desired signals and spurious signals received close together. The MGA-6x606 LNAs target WiFi and WiMAX data cards, handsets and other portable devices, while the two-stage MGA-13x16 LNAs target GSM, CDMA and W-CDMA cellular infrastructure applications such as base station radio cards.

The TGA2227-SM is a highly robust GaN Low-Noise Amplifier (LNA) covering the 2-22 GHz frequency range, and delivers >15 dB small signal gain and >+22 dBm P1dB while supporting 2 dB mid-band Noise Figure. This LNA offers a high overall electrical performance, and a high level of input power robustness for more design flexibility in the receive chain circuit protection.

Avago Technologies’ MGA-645T6 is an economical, easy-to-use GaAs MMIC Low Noise Amplifier (LNA) with Bypass/ Shutdown mode. The LNA has low noise and high linearity achieved through the use of Avago Technologies’ proprietary 0.5um GaAs Enhancement-mode pHEMT process.

This gain block amplifier covers the 20 MHz to 8 GHz frequency range. It exhibits flat gain (19 dB), a 2.5 dB noise figure, and unconditional stability over the -40C to +85C operating temperature range. It comes in a 3mm QFN package and is operational to 1.7V.
