SPINNER Filters offer reliability, performance, and value

Radio Frequency (RF) filters are crucial components in mobile communication and broadcast networks. Their primary function is to selectively allow signals of certain frequencies to pass while blocking others, thereby managing interference and enhancing the clarity and quality of the transmission. Applications include cellular base stations, broadcasting, and other RF communication systems.

Critical Characteristics and Success Factors:

  • Selectivity: The ability to precisely isolate specific frequency bands.
  • Insertion Loss: Minimal loss of signal strength through the filter.
  • Power Handling: Capability to manage the power level of the signal without degradation.
  • Durability: Performance consistency over a range of environmental conditions.

The Band-pass filter band 4/5 DTV/ATV 16.5 kW 3 1/8" SMS unflanged ensures optimal performance for signal transmission between transmitter and antenna in broadcast stations.

Band-pass filters are critical in systems that need to isolate and transmit a defined range of frequencies, such as in specific communication channels in mobile networks or distinct broadcast frequencies.

It supports the use following frequency bands : Band 4/5

The positive characteristics are briefly summarised: mask filters for DTV and ATV, for 6, 7 and 8 MHz channel bandwidth, with cross coupling (notch function), tunable within the whole UHF range, temperature compensated, installation horizontally or vertically, DC block, fan cooling.

The SPINNER quick clamp system called SMS is based on the international rigid line standards like EIA STD RS 225, 339 IEC and DIN EN 122150. The different parts are connected by coupling elements and fixed together with clamps. The advantage of the SMS system is that the customer can easily cut the rigid line to length on site, without flaring or brazing. The assembly is therefore very simple and no special tools are required. The SMS system is provided solely for indoor installation.

Our RF filters are engineered with precision, offering exceptional selectivity and low insertion loss, which are critical for efficient RF communication. Our range includes filters designed for various specific applications, ensuring that whatever your needs, we have a filter that fits. With robust construction, our filters maintain performance across a broad range of environmental conditions, making them ideal for both mobile communication and broadcast networks.

Our unique approach to RF filter design combines innovative technology with practical application insights, resulting in products that not only meet but exceed industry standards. For anyone involved in the construction or operations of RF mobile communication or broadcast networks, our filters offer reliability, performance, and value.
