Lectrosonics UFM50 UHF Filter/Amplifier Module, 20-21MHz

A high-quality and durable solution for complex antenna systems, the UFM50 UHF Filter/Amplifier Module, 20-21MHz, is an innovative product from the reputable brand, Lectrosonics. This efficient and reliable module is designed to enhance the performance of antenna systems that require extensive cable runs or distribution to multiple receivers or locations.

The UFM50 is expertly engineered to apply RF gain at the antenna, compensating for signal loss through long stretches of coaxial cable. This feature makes it an ideal choice for systems that require a strong UHF signal, such as wireless microphone systems. Additionally, it can be configured as a compact, high-performance multicoupler, used ahead of an RF splitter to offset the loss through the splitter.

The unique design of the UFM50 places RF filtering before gain, effectively minimizing intermodulation (IM) products and preventing overload. This is achieved through the use of two transmission line ceramic resonators at the input, providing filtering with a 50 MHz bandwidth. Following the filters, 12dB of gain is applied with a high-quality GasFET RF amplifier, boasting an impressive +41dBm IP3. This results in exceptional RF performance without IM or overload issues.

The UFM50 also features a switching regulator in the power supply, controlling current consumption over an input voltage range of 8 to 16 volts. This regulator ensures low current consumption and heat dissipation, making it particularly useful in portable audio mixing scenarios common in field production and ENG.

Powering the UFM50 is versatile, with options for external DC or phantom power through a coaxial cable connected to the UMC16A Multicoupler. The module's housing is constructed of cast aluminum with a brushed aluminum cover plate, ensuring durability and longevity. For secure connections in rugged field conditions and long-term installations, the UFM50 is equipped with two rugged BNC connectors and a threaded, locking power jack.

In summary, the UFM50 UHF Filter/Amplifier Module, 20-21MHz, is a reliable, efficient, and high-quality solution for enhancing the performance of your antenna systems.
