Best Radio BPF with Preamplifier

This FM preamplifier combination consists of two devices:

1. Low loss band pass filter 88 – 108 MHz  on preamplifier input side. Insertion loss just 0.35 dB

2. Wide band Low Noise Amplifier with PGA-103+

Input connectors “F” 75 Ohms

Achieves better results than two separate components. Lower NF about 0.05 to 0.1 dB. Thanks to two less connectors. Measured results with HP 8753 ES network analyzer full two port calibrated:

 

Frequency: Gain:
HF band > – 26 dB
50 MHz – 8 dB
88 – 108 MHz + 25 dB, NF=0.85 dB
145 MHz – 27 dB
432 MHz – 28 dB

 

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

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