HYTEM 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 range | 80MHz - 40 GHz |
| Attenuation dynamic | 31.5, 62 or 93 dB (110dB in development) |
| UL / DL separation | Frequency or signal direction |
| RF connectors | N or SMA |
| Control | Manual, USB, Ethernet |
| Dimensions | 19" subrack, cabinet or specific dimensions |
| Power supply | 12Vdc -> 115-230Vac |
Attenuation 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).
There 2 configurations available :
| Part Number | Frequency bandwidth | Attenuation range | Attenuation tolerance | Attenuator number | Display | Size |

Numerous applications require synchronous timing signals.
GPS signal, due to its precision and coding, offers a very rugged and reliable time base.
For laboratories, HYTEM propose different solutions for GPS signal distribution.

HYTEM 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)
Switching matrix are used to route RF signal to one or multiple outputs, using RF switches
HYTEM designs and manufacture custom matrix for your needs, up to 40 GHz
Control is performed manually or remotely (USB / Ethernet)
For more than 20 years, HYTEM has offered specific RF and Microwave systems.
