Device for investigation of electromagnetic fields of biological objects has two antennae, switch modulator, connected in sequence square detector, low frequency filter, selective amplifier, synchronous detector, integrator and voltmeter, low frequency generator that is with output connected to control inputs of synchronous detector and switch modulator. Device includes as well broadband SHF amplifier, three-winding SHF transformer and two antenna switches inputs of each of which are connected to outputs of both antennae. First earthed primary winding of SHF transformer is connected to outputs of switch modulator output of which is connected to output of antenna switch. Second earthed primary winding of SHF transformer is connected to output of the other antenna switch. Secondary winding of three-winding SHF transformer is connected to inputs of broadband SHF amplifier output of which is connected ton input of square detector. |
