Discretely tunable eleven-band noise generator

A discretely tunable eleven-band noise generator was developed based on an eleven channel switched bandpass filter. A patch antenna and a generator are manufactured of the monolithic block. Generator control is carried out over RF channel, using Bluetooth. At work of the radio-electronic equipment with confidential communication channels there is a probability of not authorized information leakage. One of the most probable channels of leak is collateral electromagnetic radiations and inducing. Noise generators are applied for protection against not authorized reading. Also noise generators are widely applied for testing and evaluating the noise immunity of radio channels of satellite communication stations.
