M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog, RF, microwave and millimeter-wave applications) has added three new products to its portfolio of discrete mixers. The ultra-small mixers provide what is claimed to be industry-leading frequency bandwidth in industry-standard surface-mount plastic TDFN packages measuring just 1.5mm x 1.2mm, enabling system developers to achieve new levels of design versatility and cost efficiency for applications including test & measurement, electronic warfare, and point-to-point wireless.
The MAMX-011021 high-IP3 mixer supports high linearity for applications including high-bit-rate transmitters and receivers. The mixer covers the 5-33GHz RF frequency range and DC-5GHz IF frequency range, integrating a single-ended cold FET structure and diplexer for about 9dB of conversion loss with +22dBm IIP3 to ensure low distortion.
The MAMX-011022 image reject mixer is targeted at medium-data-rate, long-haul, low noise systems, and is optimized for upconversion and downconversion. This mixer provides image rejection of 18dB and covers the 5-28GHz RF frequency range and DC-5GHz IF frequency range, with conversion loss of 12dB typical.
The MAMX-011023 low-noise active mixer is designed for down frequency conversion and supports very low noise of 7dB typical. This mixer covers the 4-23GHz RF frequency range and DC-8GHz IF frequency range, and supports conversion gain of 7dB typical and low power consumption at 3V/15mA.
“These new additions to MACOM’s growing portfolio of mixers are ideally suited for wideband applications for which performance, ease of use and cost effectiveness are key considerations,” claims product manager Tom Galluccio. “The frequency bandwidth coverage, small size and design flexibility enabled by these new mixers is unmatched by competing plastic-packaged products,” he adds.
The new mixers are sampling to customers now, and are being exhibited in booth 915 at the IEEE MTT International Microwave Symposium (IMS 2014) in Tampa, FL, USA (1–6 June).
