Ultra Linear Low Noise, CeramicMonolithic Amplifier, 50Ω, 0.05 to 4 GHz


Mini-Circuits’ CMA-103+ is an advanced wideband amplifier fabricated using E-PHEMT technology and offers extremely high dynamic range over a broad frequency range and with low noise figure. In addition, the CMA-103+ has good input and output return loss over a broad frequency range without the need for external matching components and has demonstrated excellent reliability. The amplifier is bonded to a multilayer integrated LTCC substrate, then hermetically sealed under a controlled Nitrogen atmosphere with gold-plated cover, eutectic Au-Sn solder, and Ni-Pd-Au termination finish. CMA-series amplifiers are capable of meeting MIL requirements for gross leak, fine leak, thermal shock, vibration, acceleration, mechanical shock, and HTOL. The testing can be done if requested.
