WLAN Low-Noise Amplifier

Product catalog summary
Description: The ALM-2812 by Avago Technologies is a dual-band low-noise amplifier (LNA) designed for WLAN applications, operating in the 2.4-2.5 GHz and 4.9-6 GHz frequency ranges. It utilizes GaAs Enhancement-mode pHEMT technology for high-frequency wideband operation with low noise figures. The device includes two LNAs in a compact 3mm x 3mm package, switchable via a single CMOS-compatible pin, requiring minimal external components.
Features: Key features include advanced GaAs E-pHEMT technology, low noise figures (0.8dB for 2.4-2.5 GHz and 1.4dB for 4.9-6 GHz), wide supply voltage range (2 to 3.6V), 50 Ohm matched input and output, high input P1dB and IIP3, power shutdown function, RoHS compliance, and a small footprint.
Specifications: At 2.45 GHz with 3.3V and 15mA, the gain is 16.7 dB, NF is 0.8 dB, IIP3 is 6.1 dBm, and IP1dB is -5.8 dBm. At 5.5 GHz with 3.3V and 23.4mA, the gain is 23.2 dB, NF is 1.4 dB, IIP3 is -2.2 dBm, and IP1dB is -12.8 dBm.
Absolute Maximum Ratings: The maximum ratings include a drain-source voltage of 3.6V, 2G drain current of 30mA, 5G drain current of 45mA, total power dissipation of 0.2W, RF input power of 5 dBm, channel temperature of 150°C, and storage temperature range of -65 to 150°C.
Electrical Specifications: For the 2.4 to 2.5 GHz band, typical gain is 16.7 dB, noise figure is 0.8 dB, and supply current is 15 mA. For the 4.9 to 6 GHz band, typical gain is 23.2 dB, noise figure is 1.4 dB, and supply current is 23.4 mA.
Performance Curves: The document includes performance curves showing gain, noise figure, IIP3, IP1dB, and supply current versus Vds and temperature for both frequency bands.
Package and Ordering Information: The ALM-2812 is available in tape and reel or antistatic bag packaging, with specific part numbers for ordering.

WLAN Low-Noise Amplifier-1

Avago Technologies ALM-2812 is a dual-band LNA designed for WLAN applications in the (2.4 - 2.5)GHz and (4.9-6)GHz frequency ranges. The LNA uses Avago TechnologiesҒ proprietary GaAs Enhancement-mode pHEMT process to achieve high-frequency wideband operation with very low noise gures.The ALM-2812 has two individual LNAs housed in a 3mm x 3mm package, each one switcheable using a single CMOS-compatible pin. All matching components are inside the module. Only one external low frequency bypass capacitor is required for proper operation, making it suitable for use in ultra-miniature WLAN cards and access points.
