In booth #930 at the IEEE MTT International Microwave Symposium (IMS 2013) in Seattle (4-6 June), M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes analog semiconductors, components and subassemblies) has introduced a new broadband sub-harmonic pumped mixer for cost-sensitive applications covering the 14-32GHz frequency range and IF frequencies from DC-7GHz.
The GaAs-based MAMX-011009 is housed in an ultra-small 1.5mm x 1.2mm six-lead plastic TDFN surface-mount package, allowing an easy, efficient and space-saving broadband solution, the firm says. The mixer has a single RF port, requires no biasing and has 2xLO and 3xLO isolation that eliminates the need for extra filtering. The device requires +15dBm of LO power, which can be attained by implementing MACOM’s MAAM-011101 (a single-bias low-cost 4-20GHz buffer amplifier).
“The MAAM-011009 was designed engineer-to-engineer with low cost and ease of use in mind,” says product manager Amer Droubi. “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 5.8GHz 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 half the LO mixing frequency, which improves isolation and simplifies system requirements.
Samples of the MAMX-011009 are available from stock.
