Lectrosonics UFM50, UHF FILTER/AMP MODULE, 50MHz BANDWIDTH [BLK 19-20]

The Lectrosonics UFM50 [BLK 19-20] provides a unique, high-performance solution for antenna systems requiring long cable runs or distribution to multiple receivers or locations. The Lectrosonics UFM50 [BLK 19-20] unit can be used to apply RF gain at the antenna ahead of a long run of coaxial cable to compensate for signal loss through the cable. Also, the Lectrosonics UFM50 [BLK 19-20] is a compact, high-performance multi-coupler that can also be configured using the UFM50 ahead of an RF splitter to offset the loss through the splitter. The Lectrosonics UFM50 [BLK 19-20] design places RF filtering before gain to minimize intermodulation (IM) products and prevent overload. Two transmission line ceramic resonators at the input provide filtering with a 50 MHz bandwidth. Following the filters, 12dB of gain is applied with a high-quality GasFET RF amplifier with an excellent +41dBm IP3. The result is outstanding RF performance without IM or overload problems. A switching regulator is used in the power supply to control current consumption over an input voltage range of 8-16 volts. The regulator maintains low current consumption and low heat dissipation which is especially useful in portable audio mixing common in field production and ENG. The Lectrosonics UFM50 [BLK 19-20] can be powered from external DC or via phantom power through a coaxial cable connected to a multi-coupler. The housing is constructed of cast aluminum with a brushed aluminum cover plate. Two rugged BNC connectors and a threaded, locking power jack provide secure connections for rugged field conditions and for long-term installations.
