The MRA-42MH+ combines a double balance mixer with a highly linear, low noise IF amplifier to provide a high gain active mixer for efficient operation from 1000 to 4200 MHz. The LO power is +13 dBm, conversion gain is 11.5 dB typical, L-R isolation of 33 dB is typical and output IP3 of dBm is typical with an IF frequency range of 10 to 800 MHz. It is packaged in a small LTCC substrate that is 0.300" × 0.250" × 0.060". Maximum operation temperature range is from -55° to 125°C. Typical applications include cellular, PCN, WCDMA, fixed satellite, defense radar and communications.
The MRA series, due to its ultra compact size, offers the additional flexibility to enable the user to install design specific components (i.e., filters, attenuators, switches, etc.) based upon the design needs. 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. These very compact active mixers have been tested to MIL requirements for gross leak, fine leak, thermal shock, vibration, acceleration, mechanical shock and HTOL.
