Sub-Harmonic Pumped Mixer requires no biasing.

Press Release Summary:

Housed in 1.5 x 1.2 mm plastic TDFN surface mount package, Model MAMX-011009 covers frequency range of 14–32 GHz and IF frequencies from DC to 7 GHz. Broadband mixer has single RF port, requires no biasing, and has optimized 2xLO and 3xLO isolation, eliminating need for extra filtering. Requiring +15 dBm of LO power, which can be attained by implementing 4-20 GHz buffer amplifier, mixer integrates 180° balanced diode topology that allows LO to be injected at ½ LO mixing frequency.

MACOM Technology Solutions Introduces Low Cost Ultra-Small Sub-Harmonic Pumped Mixer at IEEE MTT International Microwave Symposium 2013

Packaged in a compact 1.5x1.2mm plastic TDFN, the broadband mixer requires no biasing and enables customers to design systems with high IF frequency

Seattle, WA – M/A-COM Technology Solutions Inc. (MACOM), a leading supplier of high performance analog semiconductor solutions, introduced today a new Broadband Sub-Harmonic Pumped Mixer for cost sensitive applications covering the 14-32 GHz frequency range and IF frequencies from DC-7 GHz.

The MAMX-011009  is packaged in an ultra small 1.5x1.2 mm TDFN surface mount, allowing customers an easy, efficient and space-saving broadband solution. The mixer has a single RF port, requires no biasing and has excellent 2xLO and 3xLO isolation eliminating the need for extra filtering.  The device requires +15dBm of LO power that can be easily attained by implementing the MAAM-011101, which is a single bias low cost 4-20 GHz buffer amplifier offered by MACOM.    

“The MAAM-011009 was designed engineer-to-engineer with low cost and ease of use in mind,” said Amer Droubi, Product Manager. “In addition to the ultra small size and the inherit advantages of its sub-harmonic topology, this broadband mixer enables customers to design systems with high IF frequency requirements - up to 5.8 GHz in 802.11 based radios.”

The MAMX-011009, can be used for up or down frequency conversion. The mixer integrates an 180° balanced diode topology that allows the LO to be injected at ½ the LO mixing frequency, which improves isolation and simplifies system requirements for the customer.
