MM1-1857LCH-2_GaAs MMIC Double Balanced Mixer

Device Overview

General Description

The MM1-1857L is a passive double balanced MMIC mixer. It features excellent conversion loss, superior isolations and spurious performance across a broad bandwidth, in a highly miniaturized form factor. Low LO drive requirement allows operation at as low as +7dBm inputs. The MM1-1857L is available as a wire bondable chip or an SMA connectorized package. The MM1-1857H is a superior alternative to Marki Microwave carrier and packaged M9 mixers.

Features

Compact Chip Style Package (0.054” x 0.046”x0.004”)
CAD Optimized for Superior Isolation and Spurious Response
Broadband Performance
Low LO Drive Requirement
Excellent Unit-to-Unit Repeatability
RoHS Compliant
