Single Voltage E-pHEMT Low Noise 36 dBm OIP3 in SC-70

Currently Viewing:


Enhanced-mode PHEMT technology requires only a single positive voltage source. This high gain, high linearity, low noise transistor is optimized for receiver designs in cellular/PCS base stations, MMDS and other RF applications in the 450MHz to 6GHz frequency range. The ATF-54143 is packaged in miniature SOT-343 package. NF=0.55dB, Ga=17.4dB, P1dB=20.4dBm, and OIP3=36dBm at 3V, 60mA (2GHz)
