Tunable Rackmount Down-Converters

Our dual channel, Tunable Rackmount Down-Converter products offer instantaneous bandwidths of up to 3.25 GHz with 65 dB of Spurious Free Dynamic Range (SFDR). These designs are capable of block down-converting microwave signals of very large bandwidth with low distortion for high capacity data transport applications. The unique preselector provides enhanced channel selection with a monitor port as well as outstanding noise figure, while the IF limiter (approximately 11.5 dBm) ensures protection of downstream equipment. The selectable ALC allows automatic and manually adjustable input attenuation, and the fine step size provides more precise output level control.

The 1U, 19" rackmount, 'pizza box' configuration supports a wide variety of configuration options.
