Lectrosonics UFM144 UHF Filter/Amplifier Module

The Lectrosonics UFM144 UHF Filter/Amplifier Module is used to configure antenna systems requiring long cable runs or distribution to multiple receivers.

Key Features:

  • 144 MHz passband from 470 to 614 MHz
  • Ceramic resonator filters
  • GaAsFET RF amplifier
  • +27 dBm (input) and +41 dBm (output) 3rd Order Intercept
  • Switching regulator for 8-16V power at constant power dissipation to minimize heat
  • Jumpers set gain at +5dB, +8dB or +12dB
  • Powered from external DC source or DC bias from Lectrosonics multicouplers and Venue Series 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 multicoupler. 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 long term installations

The 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.

The power input on the side panel is a thread-locking (LZR type) connector
