MCA1-85+

RF Mixers Overview

The MCA1-85+ is a Level 7, surface-mount double-balanced RF mixer manufactured by Mini-Circuits. It operates within an RF and Local Oscillator frequency range of 2800 MHz to 8500 MHz, with an Intermediate Frequency range from DC to 1250 MHz. The component exhibits a typical conversion loss of 5.6 dB and provides high LO-to-RF isolation of 35 dB. Maximum conversion loss is specified at 8.2 dB, with a maximum continuous wave input power of 17 dBm.

RF Mixers Feature Summary

• Double-balanced architecture for enhanced port-to-port isolation
• Wide operational bandwidth covering 2.8 GHz to 8.5 GHz
• Surface-mount technology (SMT) package design

RF Mixers Applications

• Radar up/down converters
• RF signal mixing in microwave systems
• Frequency translation circuits

RF Mixers Procurement Notes

Verify the specific datasheet version and revision date prior to procurement, as electrical characteristics may vary between releases. Confirm that the required screening level matches project reliability standards, noting that standard catalog parts are non-hermetic SMT components. Ensure compatibility with Mini-Circuits' End-of-Life policies if long-term supply continuity is required for the production cycle.

RF Mixers Selection Notes

Select this component when a wideband double-balanced mixer is required for frequencies up to 8.5 GHz. Consider the typical 5.6 dB conversion loss and 35 dB isolation metrics against system noise figure requirements. Verify that the IF output range supports DC to 1250 MHz applications. Evaluate the SMT form factor for PCB space constraints and thermal management needs relative to the 17 dBm input power limit.

RF Mixers Part Context

The MCA1-85+ belongs to Mini-Circuits' broad portfolio of RF and microwave passive components. It is part of the MCA series of mixers designed for general-purpose communication and radar applications. The manufacturer maintains ISO 9001:2000 and ISO 14001:2004 certifications, ensuring consistent quality standards across its design and manufacturing facilities for these high-frequency devices.
