*Low noise preamplifier for mobile communication
(PCN, DECT, GSM) in 2.7V to 6V systems
*Biased monolithic microwave IC (MMIC)
*Easily matchable to 50Ω
*No bias coil needed
*Single positive supply voltage
*Low noise figure and high gain
NF=1.3dB, G=16.5dB @ 3V, 950MHz (typ.)
NF=1.7dB, G=12dB @ 3V, 1.85GHz (typ.)
*Low power consumption
*Frequency range 200 MHz ... 2.5 GHz
*Miniature package MW6 based on SOT23
