Lectrosonics UFM230, UHF FILTER/AMP MODULE, 230MHz BANDWIDTH, 538-768MHz

Lectrosonics UFM230, UHF FILTER/AMP MODULE, 230MHz BANDWIDTH, 538-768MHz

The Lectrosonics UFM230 is used to configure antenna systems requiring long cable runs or distribution to multiple receivers. The Lectrosonics UFM230 RF filtering before gain minimizes intermodulation (IM) products and prevents overload. Also, the Lectrosonics UFM230 has 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. Additionally, the Lectrosonics UFM230 has a switching regulator that can be 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 UFM230 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.
