BASE STATION REPEATERS
SB2000 BASE STATION REPEATER
DESCRIPTION
The SB2000 analogue base station offers market leading performance in a robust, reliable yet compact 2U form factor. Designed and built to exceed industry standards and all international specifications it is available in the widest range of frequency bands. When combined with the SIMOCO Solar Simulcast over IP range of products it enables the deployment of fully integrated Analogue or Digital P25 Simulcast wide area radio network solutions.
KEY FEATURES
-
Exceptional frequency coverage from 30 MHz to 960 MHz.
-
Per channel programmable parameters, inc: frequency, power, CTCSS, RF mode and channel bandwidth.
-
Extended low frequency RX discriminator and TX modulation response (DC to 3.4 kHz) enables paging and data applications.
-
Functionally independent TX and RX mean crossbanding is easily accomplished.
-
Non-predictive CTCSS decoder recognise any valid tone & transits a user associated TX tone.
-
Low current consumption on both TX & RX.
HOW IT WORKS
Performance & Reliability Advanced component, surface mount technology, encased in a rugged machined module, with an optimised PA heatsink to reduce transmitter temperature rise, combine to ensure SB2000’s outstanding performance and reliability under the harshest conditions and in continuous operation. The sensitive receiver features a wide switching bandwidth whilst maintaining good blocking, intermodulation and adjacent channel performance. The broadcast transmitter exciter module has very low spurious emission levels, and is followed by an efficient RF power amplifier.
