QUARTER transmitter on the basis of a software-defined radio system - a line of radio receivers and QUARTER transmitters on the basis of SDR technologies (Software Defined Radio).
On August 16, 2016 the press service of JSC Omsk Scientific Research Institute of Instrument Making announced release of a line of radio receivers and QUARTER transmitters on the basis of the SDR technologies (Software Defined Radio, a software-defined radio system) allowing to change characteristics of the equipment software tools.
The created radio receivers are focused on the solution of a circle of tasks in different operating conditions. Blocks of preselection and digital signal processing provided high parameters of the equipment on dynamic range, selectivity and sensitivity that guarantees achievement of high noise immunity and electromagnetic compatibility on communication hubs with a difficult interfering situation.
The line of multiple radio receivers has an ability to manage a phase and amplitude of signal outputs on commands of external devices. It allows to create direction characteristics of antenna arrays and to implement algorithms of automatic space adaptation to an interfering situation in the place of acceptance. Noise cutoff not less than on 20 dB is as a result provided at time of convergence of an algorithm of suppression no more than 1 ms.
Use of SDR technologies allows to change characteristics of receive channels, protocols of information exchange and management by a software update.
The line of the 1, 5 and 20 kW solid-state digital KV transmitters is created as the unified row with broad application of fundamental components:
- activators,
- filters,
- adders,
- interfaces,
- intensifying modules
- power supplies.
Unification of the entering blocks and nodes allows to provide technological effectiveness and to considerably reduce cost value.
In this generation of transmitters operational indicators are improved:
- reliability,
- service life,
- maintainability,
- maintenance,
- mass-dimensional characteristics.
Products can be programmed in use.
