TUNER TU-1218V1 Microwave Tuner

ESCRIPTION

The TU-1218V1 Microwave Tuner is an ultra-high performance wideband microwave tuner .The RF down converter used in conjunction with the DDS-based direct synthesizer module creates a microwave tuner featuring low phase noise and extremely fast tuning speed. This technology uncouples tuning speed from phase noise.

The TU-1218V1 is capable of tuning over the entire 12 to 18 GHz range providing both narrowband and wideband outputs, respectively. The analog outputs are suitable for direct input into an external A/D converter for special signal processing, spectral analysis or pulse

The TU-1218V1 functions for both single and multi-channel (frequency and amplitude coherent) systems. This is accomplished using a self-contained LO distribution system. This feature makes the TU-1218V1 the tuner of choice for beamforming and direction finding systems, and for a wide range of scanning/acquisition ELINT and/or EW applications.
