in-building systems

 BDA-40-SERIES  Designed and engineered to meet the fire protection codes (NFPA and IFC  standards), our Bi-Directional Amplifier (BDA) features advanced Alarm,  Monitoring & Control capabilities ensuring continuous availability of mission-critical services. Certified: FCC and IC. 

• Available in VHF, UHF, 700, 800, and 900 Public Safety bands
• Ideal for indoor applications in commercial and government buildings, parking garages, mining facilities, subway stations and tunnels
• Rack mounted or in NEMA 4/4x waterproof, stainless steel enclosures
• Low noise figure, wide dynamic range
• Visual alarms and remote failure monitoring with Graphical User Interface   

This antenna is a broadband antenna that can be used for public safety as well as in cellular bands. It makes an ideal solution for a donor antenna for a DAS system. Our In-building system antennas are designed to provide excellent coverage solutions in order for external Public Safety Radio Frequencies to propagate within buildings, tunnels or public use environments.

Features:

• Rugged design to withstand the most extreme environmental conditions.
• Extra wide bandwidth for use in multiple bands.

Our In-building antennas are designed to provide excellent coverage solutions in order for external Public Safety and cellular Radio Frequencies to propagate within buildings, tunnels or public use environments.   Our latest innovation, the UWB1304000-4310M has been designed for mounting on a ceiling or gyprock wall without the  need of a ground plane. This in-building antenna is entirely flat and gets integrated into the ceiling almost invisibly. 

The antenna’s main application includes usage for:  

• Distributed Antenna Systems (DAS) for Public Safety  
• LTE communication   
• Cellular bands in multiple stories of a building 

This compact unidirectional (1 way) RF over Fiber (RFoF) transmitter is designed for conversion of RF signals to optical signals carried over long distances. The Tx unit using an optical transmitter, converts RF to Optical signal and the Rx unit converts back to RF signal. 

The two units are connected through customer’s single mode fiber.

• Noise Figure 6 dB with LNA with MDS ~-168 dB/Hz for very low incoming signals
• Impedance of 50 Ohm and 75 Ohm
• Gain variation S21 (fo) of ±1 dB for 90° C variation
• Better linearity,
• Excellent gain flatness
• Tx, Rx and Link gain control
• Real-time diagnostic of deployed links through GUI installed on the PC

The RFoF links operate from a flexible DC power from 5 to 12 Volts.  Both the Tx and Rx units includes LNAs and variable attenuators that enable customer to adjust the Noise Figure, Input P1dB, and IP3 with wide dynamic range values. The LNA can be operated through the RFoF software allowing RF input power in the range of -100 dBm/1MHz for wideband applications, with low Noise Figure of 6 dB. The RFoF link has excellent gain flatness with 0.5dB gain tracking between different links. For special applications requiring temperature stability operation, a unique algorithm supporting 0.5 dB over 1000C has been developed.

The RF and Optical parameters: link gain, noise figure, P1dB, optical power can be remotely adjusted with help of internal microcontroller that allows for RF and Optical control, either locally or remotely.
