  • Low Noise: 0.8dB Typ for 2.4 - 2.5 GHz.
  • Low Noise: 1.4dB Typ for 4.9 - 6 GHz.
  • Wide Supply Voltage: 2 to 3.6V.
  • 50 Ohm matched Input & Output.
  • High Input P1dB and IIP3.
  • Power Shutdown Function.
  • RoHS Compliant.
  • Small Footprint: 3x3mm2.
  • Low Profile: 1.1mm max.
  • Minimal External Components Typical Specifications (25°C): At 2.45 GHz, 3.3V 15mA.
  • Gain = 16.7 dB.

ALM-2812 Dual-Band (2.4-2.5) GHz & (4.9-6) GHz WLAN Low-Noise Amplifier Data Sheet Description 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 Technologies’ proprietary GaAs Enhancement-mode pHEMT process to achieve high-frequency wideband operation with very low noise figures. 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. Surface Mount 3.0 x 3.0 x 1.
