• are offered in a wide range of enclosures: radomes, low profile, 6200 Kydex fire-retardant material, ABS high-impact, polycarbonate
Comprod can complement antenna systems with other RF components to build out the network: splitters, couplers, taps, cables, connectors, signal boosters (Bi-Directional Amplifiers) required for complete RF needs for In-Building Public Safety requirements.

  • 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.

  • Bidirectional Fiber Interface Module for BDA, RF over Fiber (RFoF)

    Frequency Range: 50-2500, 3000, 4000 and 6000 MHz
    This compact bidirectional (2 way) RF over Fiber (RFoF) transceiver is designed for Transmit/Receive antenna interfaces- applications where both an uplink as well as a downlink are required. The module employs WDM technology to use only 1 fiber link and supports 50-2500, 3000, 4000 and 6000 MHz. The RFoF link has excellent gain flatness and can be configured to have 0.5dB gain tracking between different links.
    • Noise Figure 6 dB with LNA
    • Impedance of 50 Ohm. 75 Ohm is optional with similar VSWR, by using SMA/BNC adaptor.
    • Gain variation S21 (fo) of ±1 dB for 90° C variation
    • Better linearity, excellent gain flatness, and Tx, Rx and Link gain control
    • Real-time diagnostic of deployed links through GUI installed on the PC
    • LNA ‘ON’ or ‘OFF’ is selected by the RFoF user software
    For special applications that require temperature stability operation, a unique algorithm supporting 0.5 dB over -200C to +70C may be activated. The RFoF links operate from a flexible DC power from 5 to 12 Volts. 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. Optional control card for SNMP remote management can be added at a later stage. The built-in LNA is activated through the RFoF configuration software. DOWNLOAD PDF
