Key benefits 1 dB bandwidth of 45 MHz with a defined cutoff characteristic provides selective filtering in the 703–748 MHz region, improving measurement clarity. Aluminum alloy shielded shell offers robust antiinterference protection and no outofband spurious response, while remaining compact and sturdy for easy integration. Effectively filters outofband signals, reduces noise, and increases dynamic range for RF measurements. Specifically designed for RF testing in the 703–748 MHz frequency range, supporting accurate and reliable tests. Key attributes Function: RF filter with defined 1 dB bandwidth and cutoff characteristics Frequency range: 703–748 MHz 1 dB bandwidth: 45 MHz Material / shell: Aluminum alloy shielded housing Size: Compact and sturdy Performance: Antiinterference, no outofband spurious response, noise reduction, improved dynamic range Use scenarios Use in a lab RF test bench to evaluate transmitters or filters operating in the 703–748 MHz band, paired with standard RF measurement instruments (e.g., spectrum analyzer, RF source) to assess filter performance and signal integrity. Antenna or device characterization within the 700 MHz spectrum, where clean signal reception and reduced interference improve the accuracy of impedance, loss, and filter measurements. Field validation of wireless devices operating in the 703–748 MHz range, ensuring compliant emissions and stable signal quality in realworld environments.
