ALM-2812 Dual-Band (2.4-2.5) GHz & (4.9-6) GHz WLAN Low-Noise Amplifier Data Sheet Description Features 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. x Advanced GaAs E-pHEMT 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.
