DescriptionThis Low Current Single Voltage Enhanced Mode E-pHEMT GaAs FET comes packaged in a 1.4mm x 1.2mm x 0.7mm thin miniature leadless package. ATF-541M4's small size, high linearity and low noise figure is optimized for receiver LNA or hybrid modules for handsets, Wireless LAN, fixed wireless and other RF applications in the 450MHz to 10GHz frequency range.
ATF-541M4's superior high frequency performance at 3V makes it ideal as a LNA for 5-6 GHz 802.11a and HIPERLAN/2 Wireless LAN PCMCIA PC cards.
Agilent Technologies' ATF-551M4 is a high dynamic range, super low noise, single supply E-pHEMT GAAs FET housed in a thin miniature leadless package.
The combination of small device size, super low noise (under 1dB Fmin from 2 to 6GHz), high linearity and low power makes the ATF-551M4 ideal for LNA or hybrid module designs in wireless receiver in the 450MHz to 10 GHz frequency band.
Applications of ATF-551M4 include Cellular/PCS/ WCDMA handsets and data modem cards, fixed wireless infrastructure in the 2.4, 3.5 GHz and UNII frequency bands, as well as 2.4GHz 802.11b, 5GHz 802.11a and HIPERLAN/2.
Wireless LAN PC-cards.
