For other ‘non-standard’ frequency requirements or multi-channel units, please contact the factory.
For multiple-range block up converters covering wider bandwidths please see IBUH(B) series datasheet.
For equivalent lower cost units without the full user interface please see IBU(A) series datasheet.
For Ka-Band block up converters please see IBUH(Ka) series datasheet.
For equivalent remote mount units, please see PBU(A) series datasheet.

The 19-inch 1U rack mounted IBUH(A) series of block frequency up converter units from Peak Communications are designed to takethe output of an up converter or modem at L-Band and produce an output at SHF.
The IBUH(A) series of units are mains powered and are constructed of high grade components to give the ultimate performance. Theyutilise externally phase locked dielectric resonator oscillators (XPDROs) and are far superior in stability and phase noise to voltagecontrolled oscillators (VCOs), as commonly used in other BUC designs.
High rejection performance filtering techniques are employed to ensure unrivalled spurious response.
For redundancy the IBUH(A) uses a simple CANBUS® interface and has an integral redundancy controller for 1+1 & 2+1 operation (for usewith external T1000HH, T2000HH 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.
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. With optional input power monitoring ‘built-in test’ enhancement features, compression warning alarms
and attenuation control, this product series offers the user the ultimate in controllability.

The unit has a highly stable internal reference source and will automatically detect and lock to an external 10MHz
signal, when applied.
