Helix band-pass filter BPF 2/4-2

Order number: 7000 00500400

FEATURES/ADVANTAGES

• The BPF 2/4-... is a 4-circuit helix bandpass filter with aperture coupling between the resonators.
• This filter can be used as a preselector to protect a receiver from interference from transmitters outside the bandpass limits.
• The BPF 2/4-C (C = cable) can be installed as a preselector directly in the PRO-AR4G-N, PRO-AR8G-N and PRO-AR16G-N receiver multicouplers.
• When installed in the output of a transmitter, the BPF 2/4 reduces interference signals.
• The BPF 2/4-... is adjustable over the range 144 - 175 MHz.
• Very compact due to the use of helical resonators.
• Careful material selection ensures reliable performance over a wide temperature range.
• Extruded aluminum profiles, steel frames and coaxial cables and connectors with Teflon insulation ensure good mechanical strength.
• The filter is coated with black vinyl to prevent corrosion.
