The CMD245C4 is a wideband (C, X, Ku, K band) GaAs MMIC low phase noise RF / Microwave amplifier (LPNA) housed in a leadless surface mount (SMT) package that is ideally suited for military, space, and communications systems. At 10 GHz the device delivers 18 dB of gain, a saturated output power of +21 dBm and a noise figure of 4.5 dB. Also with an input signal of 10 GHz the amplifier provides low phase noise performance of -165 dBc/Hz at 10 kHz offset. The CMD245C4 MMIC is a 50 ohm matched design which eliminates the need for RF port matching.
