The UFM230 provides a unique solution for antenna systems requiring long cable runs or distribution to multiple receivers or locations. The amplifier in the unit provides 12 dB of gain without attenuation. Gains of 5 dB and 8 dB can also be selected using the supplied attenuators. The built-in filters provide a 230 MHz passband to cover all standard Lectrosonics frequency blocks.
*Power supply not included
UHF Filter/Amplifier Module • 230 MHz passband from 537 to 768 MHz centered at 653 MHz (TV channels 25-63) • Ceramic resonator filters • GaAsFET RF amplifier • +27 dBm (input) and +41 dBm (output) 3rd Order Intercept The UFM230 is used to configure antenna systems requiring long cable runs or distribution to multiple receivers. RF filtering before gain minimizes intermodulation (IM) products and prevents overload. Two transmission line ceramic resonators at the input provide filtering with a 230 MHz bandwidth, followed by 12dB of gain using a high quality GaAsFET RF amplifier with an excellent +41dBm output IP3. A switching regulator is used in the power supply to control current consumption over an input voltage range of 8 to 16 volts. The regulator maintains low current consumption and low heat dissipation which is especially useful in mobile field production applications. 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 reliability in field production and longterm installations. The gain of the RF amplifier can be adjusted to +12dB, +8dB or +5dB and using the 0, -4 and -7 jumpers. Remove the four screws and the bottom cover for access to the internal connections and jumpers. The UFM230 is placed near the antenna to apply gain ahead of long cable runs, or to compensate for splitter loss in a multichannel signal distribution system.
