FAQs
What is a 900 MHz bandpass filter and what does it do?
L-com 900 MHz bandpass filter allows signals within the 902–928 MHz ISM band to pass while rejecting unwanted frequencies outside this range. L-com 900 MHz full band ultra-high Q bandpass filters are designed to deliver exceptional filtering performance for ISM and RFID applications. We have engineered these filters to cover the 902–928 MHz ISM band, effectively minimizing interference from unwanted signals such as cellular and paging systems.
What is the insertion loss of L-com 900 MHz bandpass filters?
L-com 900 MHz bandpass filters feature ultra-low insertion loss typically around 0.5 dB for minimal signal attenuation. We have designed their high-quality microwave cavity construction to achieve ultra-low insertion loss—typically around 0.5 dB—while maintaining precise filtering around the 915 MHz center frequency. Our 900 MHz Ultra high Q filters are built with rugged aluminum (BPF900) or weatherproof aluminum (BPF900A) enclosures.
What is the rejection performance of these 900 MHz bandpass filters?
L-com 900 MHz bandpass filters provide minimum 40 dB rejection at 815 MHz and 1015 MHz to suppress adjacent-band interference. L-com filters deliver outstanding rejection performance, with a minimum of 40 dB rejection at both low and high frequencies (815 MHz and 1015 MHz). These L-com filters provide excellent out-of-band rejection, making them ideal for industrial wireless systems, SCADA, and RFID applications that require accurate frequency control.
What is a 4-pole cavity design and why is it important?
A 4-pole cavity design provides superior filtering performance through multiple resonant sections that create sharp passband edges and deep rejection. These L-com filters feature a 4-pole cavity design that ensures superior performance with minimal insertion loss and a narrow passband for optimal signal clarity. We have designed their high-quality microwave cavity construction to achieve ultra-low insertion loss for ISM and RFID applications.
What applications use 900 MHz bandpass filters?
900 MHz bandpass filters serve industrial wireless systems, SCADA telemetry, and RFID reader installations requiring interference suppression in the ISM band. We have engineered these filters to cover the 902–928 MHz ISM band, effectively minimizing interference from unwanted signals such as cellular and paging systems.
What is the center frequency of these 900 MHz bandpass filters?
L-com 900 MHz bandpass filters feature 915 MHz center frequency positioned symmetrically within the 902–928 MHz ISM band for optimal coverage. We have designed their high-quality microwave cavity construction to achieve ultra-low insertion loss—typically around 0.5 dB—while maintaining precise filtering around the 915 MHz center frequency. L-com 900 MHz full band ultra-high Q bandpass filters are designed to deliver exceptional filtering performance for ISM and RFID applications.
