Additional Details

The YSF-322+ typically has a cutoff frequency around 322 MHz. It exhibits low insertion loss (typically less than 1 dB) in the passband and high rejection (typically greater than 20 dB) in the stopband. The filter is housed in a small surface-mount package that's suitable for automated assembly. Key specifications can be found in the product datasheet provided by Mini-Circuits, including the exact passband, stopband attenuation, return loss, and operating temperature range. Proper impedance matching is essential for optimal performance. The filter is designed for a 50-ohm impedance system.
