UU52155A(B,G), UU52172A(B), UU52158

A frequency synthesizer provides the formation of an equidistant frequency grid in increments of 3.5 MHz across three outputs in accordance with the information received from a digital computer.

                                

 The synthesizer is made on a modern element base in a hybrid-integrated version, equipped with a built-in control system with a fault signal at the levels of transistor - transistor logic.

 

  The module has high stability and reliability in a wide temperature range, resistant to a wide range of mechanical and climatic factors.
