Best Radio BPF with Preamplifier

This FM preamplifier combination consists of two devices:

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

2. Wideband 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 fewer connectors. Measured results with HP 8753 ES network analyzer full two-port calibrated:

Frequency and 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, the FM DX preamplifier and bandpass filter combination are much more immune to interference from strong out-of-band signals.
