    Bird - TX RX Systems - 11-70-01 460 - UHF Bandpass Cavity Filter, 450-470 MHz.

    20-70-01, 450-470 MHz, Series-Notch Cavity Filter passes a relatively wide band of frequencies while rejecting a very narrow band of frequencies. It is equivalent to a series-tuned circuit. Notch depth is variable from 15-25 dB. Pass and notch frequencies must be known so that the optimum loop assembly can be used. This is the best filter for very close separations (200-400 KHz) in UHF applications. TX RX bandpass cavities has an adjustable selectivity characteristics (rotatable loops) to allow a trade-off between insertion loss (0.5-3.0 dB) and selectivity. Maximum power handling is typically determined by insertion loss setting. May be cascaded to achieve an arithmetic sum of individual filter attenuation. 

    • Various Low-Loss High-Rejection Models to choose from.
    • All Loop Plate/connector assemblies are silver-or Alballoy®-plated for low IM.
    • Welded cavity construction and silver-plated tunable probe and loops give superior pass and reject characteristics.

    Frequency Range: 450-470 MHz - May requires of requiring minor 462.2375 MHz retuning

    Max Power per Cavity: 270 W, per cavity @ 0.5 dB IL

    IL: 2.5 dB 

    Impedance: 50 Ω (ohms)
