Lectrosonics UFM144-A1B1, RF AMPLIFIER WIDEBAND, 470-614 MHz
The Lectrosonics UFM144-A1B1 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 144 MHz bandwidth, followed by 12dB of gain using a high-quality GaAsFET RF amplifier with an excellent +41dBm output IP3. Power can be applied to a side panel connector, or from DC bias on the RF output jack from a receiver or multi coupler. 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 Lectrosonics UFM144-A1B1 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 long-term installations. The Lectrosonics UFM144-A1B1 RF amplifier is fixed at 12 dB of gain. Adjustments to the gain are made by inserting attenuators. The gain can be adjusted to +12dB, +8dB or +5dB using the 0, -4 and -7 jumpers. Remove the four screws and the bottom cover for access to the internal connections and jumpers.
