Doppler Measuring System

Spacek Labs Model DS-940HD is a cost-effective Doppler measuring system. The center frequency of the model shown is 94 GHz with +/- 50 MHz of bias tuning. The output power of the DS-940HD is 20 mW at the horn antenna. The Gunn oscillator incorporates a GaAs Gunn diode with an input bias of +4.5 to +5.5 VDC @ 1.0A typ. Heat is dissipated with an integrated heatsink. This assembly is delivered with a WR-10 horn antenna, an integrated isolator, circulator and a Spacek Labs W band detector, Model DW-2. It allows real-time Doppler measurements including direction (to and from radar) up to a distance of 10 feet depending on size of object. These systems are available from 18 to 110 GHz in all standard waveguide bands.
