ALM-2812

Dual-Band (2.4-2.5) GHz & (4.9-6) GHz WLAN Low-Noise Amplier

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 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. • Advanced GaAs E-pHEMT • 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: 3x3mm
2 • Low Prole: 1.1mm max.
