LMA422

LOW NOISE PHEMT MMIC FEATURES ♦ ♦ ♦ ♦ ♦ 26 GHz to 30 GHz Frequency Band 3.0 dB Noise Figure 22 dB Gain 5 dBm Output Power at Saturation +3 V Single Bias Supply LMA422 DESCRIPTION AND APPLICATIONS The Filtronic Solid State LMA422 is a low noise PHEMT amplifier that operates from 26 to 30GHz. This 3-stage reactively matched amplifier provides 22 dB nominal gain with 3dB typical noise figure and saturated power output of +5dBm. The LMA422 is designed for commercial LMDS (Local Multipoint Distribution Services) and Ka-band applications. Ground is provided to the circuitry through vias to the backside metallization.
