EMC Source SG-CG2

Heuermann HF-Technik GmbH offers the second generation of a broadband test-transmitter based on an improved comb generator and a broadband antenna.

The wideband comb generators of the SG-CG2 were developed for quick microwave receiving equipment test under various conditions. Quick and simple usage was one of the primary design goals. The SG-CG2 transmitters generate a crystal referenced fundamental frequency of 1.00 GHz and generate harmonics on whole-number multiples of the fundamental, up to 40 GHz and beyond, via non-linear elements. The generated frequency comb is then radiated by an internal wideband microwave antenna with an antenna gain of 0 dBi. A typical comb power output spectrum, measured at the antenna input, is presented in Fig. 2.
