900 MHz Full Band Ultra High Q Band pass Filters
900 MHz bandpass filters support full-band operation across ISM and RFID frequency ranges through 4-pole cavity designs operating around a 915 MHz center frequency with 35 MHz bandwidth covering the 902–928 MHz ISM band. Designed with 50-ohm impedance for bidirectional signal flow, these connectorized filters deliver maximum 0.5 dB insertion loss, minimum 40 dB stopband rejection, and 50-watt continuous-wave power handling for RF, SCADA, ISM, and RFID system designs. Available in indoor and outdoor versions with rugged aluminum housings.
FAQs
What are 900 MHz bandpass filters used for in RF systems?
L-com 900 MHz bandpass filters are designed to support full-band operation across ISM and RFID frequency ranges. These 4-pole cavity bandpass filters operate around a 915 MHz center frequency with a 35 MHz bandwidth, making them suitable for 902–928 MHz ISM band and 900 MHz RFID applications. These filters are commonly used in RF, SCADA, ISM, and RFID system designs where controlled frequency selection and interference rejection are required.
What rejection performance do 900 MHz bandpass filters provide?
L-com offer a four-section cavity design that provides a minimum of 40 dB rejection in both low and high stopbands with a minimum return loss of 15 dB across the passband. Our 900 MHz bandpass filters help reduce interference outside the passband, including unwanted cellular and paging signals, which can improve performance in electrically noisy RF environments. These filters provide a maximum insertion loss of 0.5 dB with controlled passband ripples.
What power handling do 900 MHz bandpass filters support?
L-com 900 MHz bandpass filters support continuous-wave input power levels up to 50 watts, making them suitable for a wide range of RF signal conditioning applications. The 50-ohm impedance design supports bidirectional signal flow in RF systems that require controlled frequency selection. This power handling capability supports deployment in SCADA systems, RFID networks, and industrial RF environments where higher transmit power levels are required.
What connector types are used on 900 MHz bandpass filters?
L-com have equipped the 900 MHz bandpass filters with N-type female connectors on both input and output ports, using threaded coupling to support secure RF connections. The N-type female connector interface provides reliable connectivity for indoor and outdoor RF installations in ISM and RFID applications. This standard connector type ensures compatibility with common RF cable assemblies and equipment used in SCADA, ISM, and industrial RF system designs.
What installation environments are supported by 900 MHz bandpass filters?
L-com offer both indoor and outdoor versions to accommodate different installation environments. These filters feature rugged aluminum housings with a gray finish to support use in industrial environments. We offer filters that operate over a temperature range of -40 °C to +85 °C, supporting RF filtering requirements where stable passband performance and consistent rejection characteristics are required across both protected indoor and exposed outdoor locations.
What frequency range do 900 MHz bandpass filters cover?
900 MHz bandpass filters operate around a 915 MHz center frequency with a 35 MHz bandwidth, making them suitable for 902–928 MHz ISM band and 900 MHz RFID applications. The controlled passband supports full-band operation across ISM and RFID frequency ranges while reducing interference from unwanted cellular and paging signals outside the passband. This frequency coverage supports SCADA systems, RFID networks, and industrial RF environments.
What construction features do 900 MHz bandpass filters have?
900 MHz bandpass filters feature rugged aluminum housings with a gray finish to support use in industrial environments. We have designed the indoor model for protected installations, while the outdoor version supports operation in exposed locations. The 4-pole cavity design with N-type female connectors on both input and output ports provides reliable RF signal conditioning across a temperature range of -40 °C to +85 °C for demanding ISM and RFID applications.
