A new, modular block frequency converter platform designed to accept any mix of two frequency converter modules and able to accommodate 1+1 redundancy switching in only 1RU of 19-in rack mounted space has been announced by Peak Communications.
The DBUH200 features up and down converter modules covering C, X, Ku, DBS & Ka-Bands that can be inserted/ replaced in the unit from the rear without the need to remove power or disturb the other channel, which Peak says provides flexibility in use and the ultimate in system maintainability. The design avoids the use of card-guide push type RF interconnects associated with front loaded modular systems that the company claims can suffer from performance degradation with repeated mating cycles over time and under harsh conditions.
The DBUH200 chassis units are mains powered with redundant power supplies fitted as standard. According to Peak, these are constructed from high grade components to give the ultimate stability, ripple, spurious and phase noise performance.
The DBUH200 unit is available with optional integral 1+1 redundancy switching and control for use when two identical modules are used. Units are offered with a range of optional enhancements and Peak says that it is happy to customise the units to meet specific needs.
Other features include a 10MHz external reference option fitted as standard, with automatic internal reference back-up; optional variable gain, 0-30dB in 0.1dB steps at L-Band; optional chassis mute control; and full alarm monitoring.
