3.5.5 GPS LNA (U1006, ALM-2506)
Avago Technologies’ ALM-2506-TR1G is a LNA designed for GPS/ISM/Wimax applications in the (0.9~3.5) GHz
frequency range. The LNA uses Avago Technologies’ proprietary GaAs Enhancement-mode pHEMT process to
achieve high gain operation with very low noise figures and high linearity.
Noise figure distribution is very tightly controlled. Gain and supply current are guaranteed parameters.
A CMOS compatible shutdown pin is included to turn the LNA off and provide a variable bias.
The ALM-2506-TR1G LNA is useable down to 1V operation. It achieves low noise figures and high ain even at 1V,
making it suitable for use in critical low-power GPS/ISM band applications.
The module is housed in a cost effective, small and thin package (2x2x1.1mm3).
This part is MSL Class 2 and HBM ESD Level Class 1A.
