RF mixers with high linearity and isolation

30 April 2019 Telecoms, Datacoms, Wireless, IoT

Marki Microwave has added new models to its range of high-linearity, high-isolation mixers, optimised for a variety of applications.

For S-, C- and X-band applications, the MT3L-0113H is a lower-IF variant of the MT3H-0113H triple-balanced MMIC mixer. Greater than

+30 dBm IIP3 can be achieved when paired with the ADM series of square-wave generating LO driver amplifiers. RF and LO cover 1,5 to 13 GHz, and the IF is 0,25 to 5 GHz.

With port isolations greater than 40 dB and spur suppression over 60 dBc, this latest entry to the T3 product family is ideal for high-performance radar, radio and test applications. The MT3L-0113H is available as a bare die or connectorised module, and the company can also be contacted for surface-mount QFN availability.

The MM1-0832LSM/HSM double-balanced GaAs MMIC mixers are best suited for X- through Ka-bands, with full coverage for satcom and 28 GHz 5G applications. RF is a wide 8 to 32 GHz, LO is 8 to 30 GHz, and IF spans DC to 12 GHz.

The high-linearity MM1-0832HSM provides +22 dBm IIP3 with an LO of +18 dBm, while the MM1-0832LSM offers a low drive option requiring just +8 dBm LO. Both versions feature enhanced spurious suppression and port-to-port isolations to support demanding frequency plans. They are available in surface-mount QFN and connectorised evaluation modules.
