CMA-63+ (RoHS compliant) is a wideband amplifier fabricated using HBT technology and offers high gain over a broad frequency range and with high IP3. In addition, the CMA-63+, 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 MMIC amplifier is bonded to a multilayer integrated LTCC substrate, and then hermetically sealed under a controlled nitrogen atmosphere with gold-plated covers and eutectic AuSn solder. These 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.
