MACOM's 4-23 GHz low noise active mixer

October 15, 2014

M/A-COM Technology Solutions Inc., a leading supplier of high performance RF, microwave, and millimeter wave products, today announced at EuMW 2014 in Rome, Italy, its MAMX-011023 low noise active mixer is available for sampling immediately. The highly anticipated market arrival of the 4-23 GHz MAMX-011023 discrete mixer gives system designers unrivaled flexibility to target a wide range of applications with a single mixer component. Offering the widest frequency bandwidth coverage of any product in this category, the MAMX-011023 mixer provides a versatile and cost-effective platform for a wide range of applications spanning test and measurement, electronic warfare, point to point wireless, video satellite and more.

Housed in a lead-free, ultra compact 1.5 x 1.2 mm TDFN surface mount plastic package, the MAMX-011023 mixer maximizes space savings and manufacturing efficiencies. It's designed for down frequency conversion and supports very low noise of 7 dB typical. This mixer covers the 4-23 GHz RF frequency range, has an ultra wide band IF of 8 GHz, and supports conversion gain of 9 dB typical at 12 GHz and low power consumption at 3v/15mA. This mixer can be biased from a single positive supply.

The MAMX-011023 mixer is fabricated using a GaAs process which features full passivation for increased performance and reliability, and can be used for either lower sideband (LSB) or upper sideband (USB) mixing. It integrates a FET gain element with LO and RF driving the same pin. The transconductance mixing allows a very low noise figure for an active mixer, enabling a high performing solution for real-estate constrained customers.

 "The MAMX-011023 mixer delivers excellent performance over the widest frequency bandwidth supported today in this product category," said Tom Galluccio, Product Manager, MACOM. "This wide bandwidth equips system designers to target a diverse range of products and applications with one easy-to-use device, enabling significant cost, design and component procurement efficiencies."
