RFMW announced design and sales support for a surface mount mixer from Marki MicrowaveMarki Microwave is offering a 53 GHz, surface mount mixer for low-power applications that demand high linearity. The MM1-1453LSM works well as both an up- and down-converter in test and measurement equipment, satellite communications and mmWave 5G and radar designs. It’s a passive, double balanced mixer with only 8 dB of conversion loss and IF response from DC to 22 GHz. LO to RF isolation is 56 dB. For higher LO drive levels, Marki offers the MM1-1453HSM and supports both mixers with broadband, mmWave driver amplifiers.
