Breakthrough Low Noise Amplifier


The GaAs Low Noise Amplifier (LNA) MMIC with broadband noise figure performance previously only achievable with discrete FET designs. The CMD283C3, with 0.6dB noise figure, is the first in a family of Ultra Low Noise Amplifiers.


The CMD283C3 LNA covers 2-6 GHz with high midband gain of 27 dB and output P1dB of 16dBm. The MMIC is housed in a leadless 3x3 mm surface mount package. It operates from a bias supply of +2 to +5 volts and draws a nominal 42mA. The CMD283C3 is ideally suited for S and C band receivers requiring excellent sensitivity, and as a replacement for discrete FET LNA solutions.
