Purpose of the development: The device is intended for metrology and certification materials sensory systems pulsed spin resonance methods.

Recommended application field: Instrumentation, materials science.

Technical characteristic: Specifications of the unit: - The number of pulses in the series: 1 - 3; - Pulse duration: 10-100 ns; - The pulse power up to 20 W; - The frequency of recurrence of packs: 100 Hz and 1 kHz

Advantages over analogues: Advantage of the bridge, compared to peers is its low cost, ease of management , the optimal output power, the minimum pulse width . Low cost of the bridge is provided by the use of pulsed avalanche diodes span ( ATD ) , designed to enhance the microwave pulses , instead of expensive amplifiers traveling wave tube ( TWT ) . Easy to operate is provided by selecting schemes for direct gain for the receiving unit bridge. Output power of 20 W and a minimum pulse width of 10 - 100 ns is achieved by using a two-stage pulse generator coherent .

The development stage readiness: Ready for application
