The MRA-42MH from Mini Circuits is a Wideband Mixer with an RF/LO frequency from 1 to 4.2 GHz and IF frequency from 10 to 800 MHz. It combines a double balanced mixer with a highly linear, low noise IF amplifier to provide a high gain active mixer. This mixer has a conversion gain of 11.2 dB and a high LO to RF isolation of 33 dB. This ultra-compact active mixer offers the additional flexibility to enable the user to install design specific components (i.e., filters, attenuators, switches etc.) based on the design requirement.
The Schottky diode and MMIC amplifier are bonded to a multilayer integrated LTCC substrate, and then sealed under a controlled nitrogen atmosphere with gold plated covers and eutectic Au-Sn solder. This hermetically sealed mixer is available in an ultra-compact size of 0.3 x 0.25 x 0.06 Inches and with surface mount and has been tested to MIL requirements for gross leak, fine leak, thermal shock, vibration, acceleration, mechanical shock and HTOL. It is ideal for cellular, PCN, fixed satellite, WCDMA, defense radar, defense communication applications.
