General Description

Model IFC-1090 Cable Driver Unit is designed to provide a simple cost-effective solution to the problem of combining and interfacing equipment in RF and microwave receiver systems which have different IF output frequencies. This allows the system engineer greater freedom when selecting equipment from different manufacturers, and also facilitates the re-deployment of equipment purchased for one system into other systems, reducing redundancy and idle time of expensive capital goods.   The standard unit comprises a low profile 1U high 19” rack mount enclosure with a power switch on the front panel and all connections on the rear.   These high-specification units are based on a dual conversion architecture using double-balanced mixers, which allows for a non-inverted spectrum, high image rejection and high LO isolation. This approach also makes possible non-inverting down-conversion between harmonically related frequencies (e.g. 140 to 70MHz), which is not practical using a single conversion, low-side mixing process due to LO leakage at the required output frequency. An optional external frequency reference input can be provided which can be used to lock both local oscillators to a common system reference or other equipment.   High quality filters are fitted as standard, however all units are amenable to custom filtering options which can be customer supplied, customer specified or specially sourced to meet amplitude ripple and relative group delay requirements if required for high data rate applications. Details of any special filter requirements should be provided at the time of quotation request.   For further details on specification, special options and packaging, please see overleaf.

Part Number Allocation

IFC-1090/###   IFC : Product ID (Intermediate Frequency Converter) 1090 : Product number. ### : Variant designation       Typical part Number : ‘IFC-1090/001’   The IFC-1090 product number describes a generic item which is tailored to specific applications, therefore a variant part number system is utilised instead of the configuration code system used for some of our standard products.

 

Outline Specifications

Due to the wide range of configurations and options available, only typical specifications for standard units are provided. A more detailed specification for your unit can be provided at the time of quotation or proposal.   Please refer to the full Data Sheet No.1090 for outline specification.
