The CS40-734834-CAN from Westell Technologies is a Bidirectional Amplifier (BDA) that operates from 798 – 824 MHz (uplink) and 768-776 MHz/851-869 MHz (downlink). It delivers an output power of 2.5 W (~34 dBm) with a gain of 75 dB and has a noise figure of less than 7 dB. This amplifier represents the next revolution in public safety DAS designs, offering the most flexible platform available on the market. It supports both analog and digital modulation technologies with an independent gain control per built-in filter. This Class A/B amplifier includes self-healing intelligent oscillation management, adjustable frequency filters, a dedicated FirstNet filter profile, built-in isolation test, protection capabilities, battery backup, and communication links. It allows for uplink and downlink squelching for every filter.
The CS40-734834-CAN has a fully-featured, easy-to-use web GUI with NFPA/UL2524 alarm capabilities. It has built-in annunciator communication link with an optional remote annunciator panel, and built-in battery backup circuitry for remote monitoring and reliable operation, especially under low-voltage conditions. This amplifier includes an AC charger. It is available in an IP65/NEMA-type 4 wall-mount enclosure that measures 18.6 x 14.9 x 7.3 inches with 4.3-10 (female) connectors and RJ45 (Jack) for web-browser-based user interface.
