The CMD247 is a wideband (Ka, Q, U band) GaAs MMIC low phase noise RF / Microwave amplifier (LPNA) ideally suited for military, space and communications systems. At 35 GHz the amplifier MMIC delivers 13 dB of gain, a saturated output power of +15 dBm and a noise figure of 5 dB. Also, the amplifier provides low phase noise of less then -160 dBc/Hz at 10 kHz offset. The CMD247 MMIC is a 50 ohm matched design which eliminates the need for external DC blocks and RF port matching. The CMD247 also offers full passivation for increased reliability and moisture protection.
