The DS038877-1 from TX RX Systems is a Bi-directional Amplifier (BDA) System that operates across the 700 and 800 MHz bands, including the FirstNet band. It delivers an output power of 2 W with a gain of up to 90 dB and has a gain adjustment range of 30 dB. This BDA allows passbands to be turned ON/OFF independently and supports independent power and gain control per band. It supports both digital and analog modulation, including P25 phases 1 and 2, and utilizes sharp SAW filtering to reduce interference from adjacent RF signals. The BDA has integrated intelligent oscillation management and self-healing features and shuts down in the event of non-correctable conditions. It also includes VSWR antenna monitoring built-in battery charging and alarm circuitry.
The DS038877-1 can operate on both AC (110 V) and DC (24 V) supplies and is capable of redundant power supply. It includes an RJ-45 Ethernet interface with web GUI and supports SNMP. This BDA is available in an IP65-rated NEMA type-4 enclosure that measures 480 x 400 x 125 mm with 4.3-10 (female) connectors. It is NFPA 72/1221 compliant with form-C contacts for fire panel connection.
