NuWaves Engineering has added a custom filter amplifier to its growing line of amplifiers and other RF products. NuWaves' new Hilna CF amplifier is designed to allow end users the ability to select their own unique custom filter (lowpass, highpass, bandpass or band-reject) for this unique low noise, high gain, high linearity and broadband amplifier. This new amplifier-filter combination is custom designed to the end user's application, providing the capability to reject interfering signals across a selected frequency of bandwidths.
