The NC3404 is a 2 GHz to 4 GHz coaxial AWGN noise source with an ENR of 30 to 36 dB and a flatness of ±0.75 dB. It features a VSWR of less than 1.3:1 and a maximum bias current of 30 mA. The device includes a built-in isolator to ensure constant output impedance and protect against incident RF power up to 1 W average and 100 W peak. Standard RF output is an SMA female connector, and bias input is a BNC female connector, with optional connectors available. It operates from a +28 VDC supply with typical current draw of 12 to 15 mA and has a noise output rise and fall time of less than 1 µs.
The NC3400 Series coaxial AWGN noise sources are an excellent choice for applications requiring high ENR and immunity to large incident RF power, such as ATE, radiometer, and radar systems. The calibration accuracy and flatness of the NC3400 Series noise sources are enhanced by their low VSWR. The built-in isolator provides almost constant output impedance as the noise source bias is switched on and off. The isolator also protects the noise diode from incident RF power (consult the factory for higherpower units).
An SMA female connector is standard for the RF output and a BNC female connector is standard for the bias input. Other connectors are available as options.
