High Intercept Low Noise Amplifier for the 1930 1990 MHz PCS Band using the Agilent ATF34143High Intercept Low Noise Amplifier for the 1930 - 1990 MHz PCS Band using the Agilent ATF-34143 Low Noise PHEMT (4 V, 40 mA)
Application Note 1191
Introduction Agilent Technologies’ ATF-34143 is a low noise PHEMT designed for use in low cost commercial applications in the VHF through 6 GHz frequency range. The ATF34143 is housed in a 4-lead SC-70 (SOT-343) surface mount plastic package. The 800 micron gate width of the ATF-34143 makes it ideal for applications in the VHF and lower GHz frequency range by providing low noise figure coincident with high intercept point. The wide gate width also provides lower impedances that are easy to match. This application note describes the use of the ATF-34143 described in a low noise amplifier optimized for the 1930 to 1990 MHz band for PCS applicatio
