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)

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.
