Single Voltage E-pHEMT Low Current Low Noise 24.2dBm OIP3 in SC-70

Currently Viewing:

Enhanced-mode PHEMT technology requires only a single positive voltage source. This low noise, high gain, high linearity transistor is optimized for low current receiver designs in cellular/PCS and WCDMA handsets, mobile wireless devices and other low current RF applications in the 450MHz to 6GHz frequency range.

The ATF-55143 is packaged in miniature SOT-343 package


NF=0.6dB, Ga=17.7dB,
P1dB=14.4dBm, and
OIP3=24.2dBm at 2.7V, 10mA (2GHz)
