Outdoor 2m bpf with VLNA 144MHz-146MHz EME Terrestrial

This combination consists of:

4. Two clamps.

Achieves better results than two separate components. Lower NF about 0.05 to 0.1 dB. Thanks to two less connectors.


Measured results with HP8753ES network analyzer full two port calibrated:

Frequency: Attenuation:
1.82 MHz - 75 dB
3.8 MHz - 82 dB
7.1 MHz - 80 dB
14.15 MHz - 67 dB
21.2 MHz - 62 dB
28.4 MHz - 55 dB
50.1 MHz - 40 dB
54 MHz - 37 dB
70 MHz - 29 dB
70.5 MHz - 28.5 dB
FM: 88 MHz - 18.5 dB
FM: 98 MHz - 12.3 dB
FM: 108 MHz - 5.3 dB
144 MHz + 25 dB NF = 0.7 dB (Calculated bandpass filter insertion loss)
144.1 MHz + 25 dB NF = 0.7 dB (Calculated band pass filter insertion loss)
146 MHz + 25.1 dB NF = 0.7 dB (Calculated band pass filter insertion loss)
288.2 MHz - 34 dB
296 MHz - 36.5 dB
432.1 MHz - 46 dB
440 MHz - 44 dB
IP3out > 37 dBm
Power consumption:  +10-15 V / 100 mA

These excellent results were achieved by careful selection of components and design.

Thanks to input filtering this preamplifier and band pass filter combination are much more immune to interference from strong out-of-band signals. Compared to output filtering.
