Microwave Power Sensors

Anritsu (Morgan Hill, CA) offers MA24108A/ MA24118A microwave USB power sensors that provide average power measurements from 10 MHz to 18 GHz over 60 dB of dynamic range. Employing a dual-path architecture, they can measure CW, multi-tone, and digitally modulated signals used in aero space/defense systems. They have built-in external trigger circuitry and an MCX connector interface to receive triggers from external stimuli. They also include a microcontroller, signal conditioning circuitry, ADC, and power supply.

Three modes of operation are available: continuous average, scope, and time slot. The sensors feature an operating temperature range of 0 to 55 °C, a high damage level of 33 dBm, and ESD protection. They are compact enough to be carried in shirt pockets or laptop cases.
