DESCRIPTION AND APPLICATIONS The Filtronic Solid State LMA420 is a low noise PHEMT amplifier that operates from 21 to 24GHz. This 3-stage reactively matched amplifier provides 22dB nominal gain with 3dB typical noise figure and saturated power output of +5dBm The LMA420 is designed for commercial mm-W (millimeter-wave) PCN/PCS applications. Ground is provided to the circuitry through vias to the backside metallization. FEATURES ♦ 21 GHz to 24 GHz Frequency Band ♦ 3 dB Noise Figure ♦ 22 dB Gain ♦ 5 dBm Output Power at Saturation ♦ 12 dB Input/Output Return Loss ♦ +3 V Single Bias Supply
