Microwave Service Company develops weatherproof block downconverters
Microwave Service Company launched its new line of block downconverters, available for operation in the 2.0GHz-2.7GHz band as well as the UHF bands (450MHz-850MHz). The converters are designed to convert digital COFDM and analog transmissions to their respective signal range, allowing user to change bands quickly depending on their needs and equipment setup for various field applications.
Microwave Service Company’s 5/6/7 GHz block downconverter is a single conversion BDC with low phase noise and high linearity.The front panel includes an LNA and ceramic filter that delivers a 3.5dB noise figure with a minimum conversion gain of 24dB. The UHF model also delivers a 3.5dB noise figure with an overall typical conversion gain of 24dB. DC power can be supplied locally or remotely via the coax to the IF output to both versions.
Designed for maximum protection of its block downconverters, Microwave Service Company is also unveiling new weatherproof enclosures.
Microwave Service Company’s downconverters are also energy-efficient, whether they be 2.0Ghz or 5.8Ghz, draw 160 mA or less of power, making them very efficient in operation. The 2Ghz unit has an output impedance of 50 ohm while the UHF converter has an output impedance of 75 ohm. All versions are RoHs compliant.
