DEM1691ULNA - DEMI

DEM1691ULNA (DEMxxxULNA) Ultra Low Noise Amplifier

The DEM ULNA is a series of Ultra Low Noise Amplifiers intended to be used for Radio Astronomy applications, amateur EME communications or weak signal satellite reception This series of ULNA’s produced by Down East Microwave Inc. share a common design from 900 through 1800 DataShee MHz. Each model listed above is optimized depending on the frequency require.

Features

As are receive only and do not provide any RF bypass switching circuitry. Standard gains of our ULNAs range from15 - 17 dB depending on frequency. All noise figures for this series of ULNAs are below 0.4dB. The ULNAs are adjusted on an individual basis for the best performance possible. Our ULNA design incorporates a low loss series inductor input circuit and a resistive loaded output circuit. During testing, the input circuit is optimized for gain and noise figure. The resistive loaded output circuit, is adjusted to control the gain and is tested for a constant wide bandwidth output impedance.
