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.
