Technical content

These filters are manufactured on quartz, which provides optimal temperature performance and are available from 80 -1600 MHz. This TCRF is designed for narrowband IF filtering such as in satellite transponders, directional finders and anti-jam modems. Other packaging styles are available for more rugged environments and applications. Standard part numbers as well as custom solutions are available. Please contact sales for more information.

Reference frequency at 25°C. Computed as mean of the 3 dB frequencies. 2. All dB values are referenced to the insertion loss value. 3. Typical shift of frequency response with temperature is: Δf=(T-Tref)*Tc*Fc Notes:

  • Recommend 2% or better tolerance matching components. Typical inductor Q=40.
  • Optimum values may change depending on board layout. Values shown are intended as a guide only. MAXIMUM RATINGS MATCHING CIRCUIT Parameter Min Max Units Storage Temperature -40 85 °C Input Power Level - 10 dBm
