CMD298C4 17-25 GHz Low Noise Amplifier Product Overview The CMD298C4 is a highly efficient GaAs MMIC low noise amplifier housed in a leadless 4x4 mm surface mount package. The CMD298C4 is ideally suited for EW and communications systems where small size and low power consumption are needed. The device is optimized for 21 GHz and delivers greater than 27 dB of gain with a corresponding noise figure of 1.4 dB and output 1 dB compression point of +8 dBm. The CMD298C4 is a 50 ohm matched design which eliminates the need for external DC Key Features blocks and RF port matching.
