Additional Details

SAW filters like the B39172-B1658-B510-W03 are designed for specific frequency bands. The precise specifications, such as center frequency, bandwidth, insertion loss, and attenuation, are critical for proper operation. Engineers selecting this filter must ensure that these parameters match the requirements of their application. The filter's impedance matching characteristics are also important for minimizing signal reflections and maximizing power transfer. EPCOS (TDK) provides detailed datasheets that outline these specifications to assist designers in selecting the appropriate filter for their needs. The operating temperature range and maximum power handling capability should also be considered to ensure reliable performance in the intended environment.
