About
Astra Microwave Products, founded in 1991 and headquartered at Astra Towers in Kothaguda near HITEC City, Hyderabad, is one of India's major private radar and microwave subsystem manufacturers for the defence and space sectors, and it operates its EMI/EMC facility as an accredited service available to external customers as well as its own programmes. The laboratory holds NABL accreditation to ISO/IEC 17025:2017 under laboratory identification TC-6264. Its shielded semi-anechoic chamber measures 6.7 by 6.1 by 3.75 metres with shielding effectiveness better than 100 dB and covers 10 kHz to 40 GHz, with radiated susceptibility fields to 60 V/m - a specification built for airborne and shipborne radar hardware rather than commercial electronics. The test programme is correspondingly military: the MIL-STD-461 method set run here includes conducted emissions on power leads (CE01, CE03, CE101 and CE102), radiated emissions in both magnetic and electric field modes plus antenna terminal emissions, conducted susceptibility on power leads, antenna ports and by bulk cable injection including intermodulation and transient methods, and radiated susceptibility from 14 kHz to 40 GHz. Beyond EMC proper, the facility measures aircraft electrical power characteristics to MIL-STD-704 revisions D, E and F, and performs shipboard DC magnetic field testing - both capabilities that are rare outside national defence laboratories. The company is chaired by Dr. Avinash Chander, former Director General of DRDO, under managing director Dr. Maram Venkateshwar Reddy. Specialisations are radar and microwave subsystems, airborne and shipborne defence electronics, space hardware, meteorology and homeland security systems.
