Saras RF Splitters & Combiners
Saras Antenna Splitters and Combiners
De 1 naar 2 passieve splitter/combiner (SLC007) is leverbaar in N-type of BNC connector. De operationele frequentieband loopt van 30 tot 930Mhz. De splitter wordt gebruikt in meerkanaals systemen waarbij de (actieve) ontvangsantennes worden uitgesplitst naar meerdere ontvanger inputs. Tevens kan de splitter als combiner worden gebruikt. Om een draadloze microfoon in meerdere ruimten te kunnen ontvangen kunnen per ontvangeringang de antennes uit verschillende ruimten worden gecombineerd.
De 1 naar 4 passieve splitter/combiner (SLC006) is leverbaar in N-type of BNC connector. De operationele frequentieband loopt van 30 tot 930Mhz. De splitter wordt gebruikt in meerkanaals systemen waarbij de (actieve) ontvangsantennes worden uitgesplitst naar meerdere ontvanger inputs. Tevens kan de splitter als combiner worden gebruikt. Om een draadloze microfoon in meerdere ruimten te kunnen ontvangen kunnen per ontvangeringang de antennes uit verschillende ruimten worden gecombineerd.

Saras In Line Amplifiers
De In Line Amplifier wordt gebruikt om kabelverliezen, welke optreden bij lange kabellengtes, op te heffen. De versterker, met een werkzame bandbreedte van 24Mhz, wordt gevoed door de DC spanning op antenne ingang van de ontvanger. Deze voedingsspanning wordt ook verder doorgegeven zodat ook actieve antenne's nog zijn te combineren. De SLA002 kan worden uitgevoerd op BNC of N-type connectoren. Frequentieband en mate van versterking zijn op klant-specificaties.

Saras Antenna Combining System
SARAS Technology Limited manufactures a state of the art multi-area
diversity distribution system for radio MIC operation across multiple
electromagnetically isolated areas. This system has been successfully
used on many reality TV programs such as the BBC’s ‘Dragons Den' and
Channel 4's ‘The F Word’.
The SAA002 UHF Multi-Area Diversity
Antenna Distribution System allows the user to configure reliable Radio
MIC operation where the same transmitter is moved across a number of
areas, electromagnetically shielded from one another. The system
combines up to four pairs of diversity antennas, located in different
areas, process the combined signals and then outputs four pairs of
signals to drive diversity receivers. The unit is mains powered and
provides for switchable +12V DC feed on the antenna inputs to power the
active antennas, if used. These 12V supplies for powering any active
antennas or other in line devices are short-circuit protected by means
of external fuses. The unit’s switching power supply is designed to
operate properly from any AC power source 100-240V, 50/60 Hz without
adjustment.
Saras IEM Distribution System
The IEM8000 system consists of a base unit and a number of aerial
amplifiers. The base unit, housed in a 19in 2U rack, combines up to
eight IEM channels and then split out to the eight outputs. The input
connectors to the base unit are BNC and N-Type for the outputs. The
base unit can be located centrally together with the IEM transmitters.
Each
output of the base unit is connected to an antenna located in the zone
to be covered via a low loss cable. A linear aerial power amplifier,
located just before each antenna, is used to overcome the RF losses
such that an RF power level of 50mW/channel is available at the antenna
inputs. The aerial amplifiers are line powered and are located as near
as possible to the antennas.
