Power Detector Shows Wide Range at IMS

June 15, 2018
MACOM unveiled its broadband power detector with a wide dynamic range spanning −15 to +15 dBm from 5 to 44 GHz.

Measurement solutions were prevalent on the 2018 IEEE IMS exhibition show floor, especially those reaching into the millimeter-wave range. For those measuring wideband power, for example, MACOM unveiled its new model MADT-011000 with a high dynamic range of 30 dB from 5 to 44 GHz. Visitors to booth 1125 had an opportunity to see this high-performance detector among the many products on display.

The power detector, available in both packaged and chip forms (see figure), draws a mere 70-μA current from a +4.5-V dc supply in single-ended, internally matched (to 50 Ω) operation, and features temperature compensation with reference diodes in differential mode of operation. It comes in either a 3-mm, 16-lead QFN package or as a bare die measuring just 1.00 × 0.75 × 0.1 mm. The chip includes electrostatic-discharge (ESD) protection for ease of handling.

Whether in the package or a bare die, the detector can measure power levels from −15 to +15 dBm over the wide frequency range of 5 to 44 GHz with low current consumption. The return loss for the packaged detector is 15 dB, while the return loss for the chip detector is 11 dB.

Graham Board, senior director of product marketing at MACOM, said, “The wide bandwidth and dynamic range, very low power dissipation, and external directional coupler makes this an ideal solution for both narrow and wide bandwidth power control circuits. It is anticipated that this one power detector will cover all of the high-volume wireless backhaul bands from 5 to 44GHz, significantly simplifying component selection and circuit design for the radio designer.”
