144-148 Filtered Low Noise Amplifier

Regular price $81.00


This is a small and cost-effective Filtered Low Noise Amplifier with a passband from 144 to 148 MHz with excellent rejection of FM band. Within the 2m band, the Gain is 20 dB while the Noise Figure is less than 1 dB.

It filters and amplifies signals with frequencies from 144 MHz to 148 MHz in North and South America plus Hawaii, Asia and Oceania. It includes the frequencies 144 MHz to 146 MHz in Europe, Africa, and Russia. 

The RF Input has an ESD diode for static protection. The device can be powered using either the Micro USB port or with a DC supply using the two-pin header. The DC supply can vary over a wide range from +4 VDC to +12 VDC.
