This document discusses radio frequency (RF) and microwave absorbers, shielded enclosures, and anechoic chambers. It provides details on the types of RF absorbers manufactured, including pyramidal, wedge, convoluted, and weatherproof absorbers. It also discusses shielded enclosures for RF shielding with effectiveness up to -100 dB from 10 kHz to 40 GHz. Finally, it describes RF anechoic chambers which use absorbers to minimize reflections and shield tests from external noise in order to accurately measure antenna parameters and radiation emissions.

- 1. RF ABSORBERS - RADIATION ABSORBENT MATERIAL (MANUFACTURE FOLLOWING TYPES OF RF MICROWAVE ABSORBERS – PYRAMIDAL, WEDGE, CONVOLUTED, WEATHER PROOF, MULTILAYER BROADBAND, WALWAY) SHIELDED BOX & CHAMBER - RF SHIELDED ENCLOSURE (MANUFACTURE SHIELDED ENCLOSURE –PAN/MODULAR/SANDWITCHED WITH SHIELDING EFFECTIVENSS OF -100 dB FROM 10 KHz TO 40 GHz) RADIO FREQUENCY & MICROWAVE – FREQUENCY TESTING SOLUTIONS (ANECHOIC CHAMBER, ABSORBERS, SHIELD BOX, MICROWAVE COMPONENTS) The absorber is treated to provide a finished product that meets the fire retardant requirements of NRL specification 8093 tests 1, 2 and 3 and other International specifications. The typical nominal size of Pyramidal RF Absorber ranges between 4 in. (102mm) and 36 in. (920 mm). Base dimensions are 600 x 600 mm. FEATURES Quite Zone better then - 52 dB. Temperature resistant. 0.5 Watt/in2 or 775 Watt/m2 Power Handling. Tested as per IEEE standards Fire retardant as per NRL 8093 Long product life up to 25 years. ROHS compliance for safety. High Attenuation from 20 dB to 55 dB from 100 MHz to 40 GHz. APPLICATION For the measurement of radio noise emission. Microwave Absorbers used in making Microwave Anechoic chambers for performing measurements like Antenna pattern, and to obtain quite zone in wide frequency range inside chamber. Weather proof Absorbers are used for outdoor Applications.
- 2. (ANTENNA PARAMETERS – RADIATION PATTERN, GAIN Etc TESTING, RADIATION EMISSION TESTS) . An RF anechoic chamber is usually built into a screened room, designed using the Faraday cage principle. This is because most of the RF tests that require an anechoic chamber to minimize reflections from the inner surfaces also require the properties of a screened room to attenuate unwanted signals penetrating inwards and causing interference to the equipment under test and prevent leakage from tests penetrating outside. RF anechoic chamber shields a test setup from RF noise from external environment and absorbs reflected signals generated inside the chamber. We undertake the projects on turnkey basis, including design of chambers, supply of absorbers, installation & Characterization of the chambers for specific applications. ANECHOIC CHAMBER - RADIO FREQUENCY- MICROWAVE ANECHOIC CHAMBER COMPONENTS - RADIO FREQUENCY- MICROWAVE (LAB MEASUREMENTS, BROADCASTING, FREQUENCY MEASUREMENT) LIST INCLUDES:- 1) Microwave Test Bench 2) Antennas 3) Waveguide Components & Adapters 4) RF Cables 5) Any customized or similar product. APPLICATIONS:- 1) Waveguides are used in scientific instruments to measure optical, acoustic and elastic properties of materials and objects. In a radar, a waveguide transfers radio frequency energy to and from the antenna. 2) Our antenna solutions range from industrial to military applications and include Line-Of-Sight tactical communications, vehicular mount, GPS, telemetry, and mesh networks. 3) These Test Benches allows carrying out practical frequency tests at extremely low cost. Also, students use these for their Lab Measurements.
