Attenuator banks

Attenuator banks

Syst attenuationHYTEM offer different RF attenuation systems that allow to perfom simultaneous types of tests on multiple RF links (handover for instance).

Multiple configurations are available :

Attenuation systems - Capabilities
Frequency range80MHz - 30 GHz (40GHz in development)
Attenuation dynamic62 or 93 dB (110dB in development)
UL / DL separationFrequency or signal direction
RF connectorsN or SMA
ControlManual, USB, Ethernet
Dimensions19" subrack, cabinet or specific dimensions
Power supply12Vdc -> 115-230Vac

Attenuation matrix

Attenuation matrix

CaptureAttenuation matrixes allow to send one or multiple signals to one or multiple outputs, while changing power level of each signal individually.
Different from handover simulation, fast fading requires very fast attenuation change speed. In handover simulation subracks, orders are executed on a PC, then transmitted to subrack (through Ethernet or USB), which will add latency.
To allow faster speeds, attenuation matrixes integrate an embedded industrial PC, from which scenarios are run. Attenuation variation speed of 25 μsec can be achieved (against 25 to 50 msec for handover simulation subracks).

legacymanulegacyautoHYTEM has designed atténuation systems (subracks, matrix) for 20 years.

Initial products were based on manual attenuators (rotary), but were quickly replaced by remotely controlled products

Manual systems are still manufactured on request (please also check Variable attenuators)
