The 19 inch 1U rack mounted IBDH(A) series of Block Frequency DownConverter units from Peak Communications are designed to take the incoming SHF signal and produce an output at L-Band that is suitable for direct connection to an L-band demodulator or for further conversion typically by a P7001 synthesised DownConverter.
The IBDH(A) series of units are mains powered and are constructed of high grade components to give the ultimate performance. They utilise Externally Phase Locked Dielectric Resonator Oscillators (XPDROs) and are far superior in stability and phase noise to Voltage Controlled Oscillators (VCOs), as commonly used in other BUC designs.
For redundancy the IBDH(A) uses a simple CANBUS® interface and has an integral redundancy controller for 1+1 & 2+1 operation (for use with external R1000HH, R2000HH series switch units), also compatible with the RCUH100/ RCUH200 series 1+1/ 2+1 ‘stand alone’ redundancy controllers. For N+1 systems the RCU1002 series is offered.
These converters are single stage converters apart from the IBDH340 which is a dual stage unit. The unit incorporates a graphics display module, membrane keyboard and features a clear and intuitive control and configuration menu fully utilising the unique graphics display.
