Procom Band Pass Filter BPF 70/3

Procom Band Pass Filter BPF 70/3

Features :

• The BPF 70/3 is a 3 x ¼ λ resonator band-pass filter with internal coupling between the resonators.
• This filter can be used as a preselector to protect a receiver against interference from transmissions out of the passband, or it can be used to reduce spurious output from a transmitter with up to 50 W output power.
• The filter can be tuned within the entire 380 – 470 MHz band. Careful design and choice of materials ensure reliable operation over a wide temperature range.
• The housing is made of extruded aluminium, the chassis of brass, and teflon insulation has been used in the coaxial cables and in the connectors.
• The filter is black vinyl coated to prevent corrosion.
