CHELMSFORD, Mass. – Custom MMIC in Chelmsford, Calif., is introducing the CMD283C3 ultra-low-noise amplifier monolithic microwave integrated circuit (MMIC) to help reduce unwanted phase noise and improve signal integrity and target acquisition in RF and microwave applications like aerospace and defense radar systems.
The CMD283C3 provides an 0.6 dB noise figure, outperforming all other LNA MMICs, and rivalling discrete component implementations. It operates over a frequency range of 2 GHz to 6 GHz (S & C-band) and has output IP3 of +26 dBm.
Custom MMIC also is introducing four members of a new gallium arsenide (GaAs) MMIC digital attenuator family. The CMD279 and CMD280 operate up to 30 GHz with 5-bit control. Attenuation range is up to 15.5 dB. Two, 2-bit attenuators, the DC-35 GHz CMD281 and DC-40 GHz CMD282, offer coarser control in 2 and 4 dB steps respectively. All four devices offer input IP3 of +42 dBm.
Their latest distributed amplifier, the DC-20 GHz CMD249P5, offers a positive gain slope with nominal 12 dB gain. The GaAs device features output Psat of +30 dBm and output IP3 of +38 dBm.
Custom MMIC also is enhancing the company's line of low-phase noise amplifiers to operate to 40 GHz with low phase noise performance down to -165 dBc/Hz at 10 kHz offset.
They serve as local oscillator (LO) drivers or receiver amplifiers in a variety of phased array radar, electronic warfare (EW), military radio, instrumentation, and aerospace and space communications designs.
