At EuMW 2014, M/A-COM Technology Solutions announced that the MAMX-011023 active mixer is now sampling. According to the company, the 4–23GHz mixer provides a wider frequency coverage than competing mixers. The cost-effective mixer is suitable for a variety of applications, including test and measurement, electronic warfare, point-to-point wireless and video satellite.

Providing a space saving and efficient solution, the mixer is housed in a lead-free, compact 1.5x1.2mm TDFN surface mount plastic package. Designed for down frequency conversion, the MAMX-011023 supports noise of 7dB typical. Featuring a low power consumption of 3V at 15mA, the mixer has a wide band IF of 8GHz, supports conversion gain of 9dB typical at 12GHz and can be biased from a single positive supply.

The MAMX-011023, which can be used for either lower sideband or upper sideband mixing, is fabricated using a GaAs process which provides full passivation for improved performance and reliability. An FET gain element with LO and RF driving are integrated within the same pin.

“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.”
