70cm 430–450MHz Ultimate Receiving BandPass Filter Low Loss

Put this super low loss 70cm 430–450MHz ultimate receiving bandpass filter before any wideband LNA to prevent overloading of any out-of-band signals. Bandpass filter will almost nothing disturb the noise performance of any wide-band pre-amplifier which is especially important in terrestrial and EME communications. It will further ensure smooth operation in the presence of strong out-of-band signals. The position of connectors allows outdoor mounting by order.

What others say about 70cm 430–450MHz Ultimate Receiving BandPass Filter

“I received the 2 x BPF144 filters and they work very well. They have resolved my out-of-band RFI problem and made my 2M EME station more sensitive to weak signals. The small O.2 dB insertion loss is more than compensated by having the preamps operating in their linear region and not in compression caused by strong local FM broadcast and Aircraft radio systems. It’s a pleasure to do 2M EME now.”
73 Paul W2HRO

“LNA test: Two LNAs have the same behavior. Gain at 144MHz 25.96 dB, NF 0.68, LNA only Gain 25.73 dB, NF 0.88 dB, LNA + filter. Results seem consistent and confirm the 0.2 dB loss of the filter.
-1db compression point happened with -3dBm input signal level.”
73 Franco I2FAK

“Many thanks, good news today all staff well arrived! I made DUTs on test this PM to the VNA HP 8510C and to the noise analyzer, congratulations all specs are very well respected! NF it is a bit better 0.28dB on 144MHz, for the others bands as you say.”>
