The Anritsu MA24105A is an inline peak power sensor engineered for accurate measurement of average and peak power in RF and microwave signals from 350 MHz to 4 GHz. Using a dual-path architecture, it delivers True-RMS measurements across its entire frequency and dynamic range, supporting CW, multi-tone, and digitally modulated signals including GSM/EDGE, CDMA/EV-DO, W-CDMA/HSPA+, WiMAX, and TD-SCDMA. The inline configuration enables direct power monitoring without signal path disruption, making it ideal for radar, communications, and electronic warfare applications.
