MACOM launches Up-Converter for 28 to 34GHz Point-to-Point Radio

LO leakage and high linearity means minimal filtering

MACOM has announced a new integrated up-converter suited for 28 and 34GHz point-to-point radio applications. Assembled in a lead-free 4mm 24-lead PQFN plastic package, the device has a typical conversion gain of 12dB, and an image rejection of 15dBc and is integrated with a LO doubler, LO buffer amplifier, and RF buffer amplifier.

The device is said to offer industry's leading LO suppression that eliminates the customers' need for a Tx Filter.

"The MAUC-011003 is ideal for customers looking for a high performance up-converter for use in current and next generation point-to-point microwave radios," said Michael O'Driscoll, product manager. "The exceptional LO leakage performance and high linearity enables the implementation of high order modulation schemes using direct up-conversion or using an IF with minimal LO filtering, hence reducing the complexity and cost of the overall system for our customers."

The MAUC-011003 delivers turn down trajectories optimised to maintain linearity and 2xLO leakage over the gain control range and is ideally suited for 28 to 34GHz bandwidth for point-to-point radios under both LSB and USB operation and Ka-Band VSAT applications.
