Latest Patents

Kangaslahti holds a patent for a predistortion linearizer circuit. This circuit comprises an amplitude distorting part (AM/AM) and a phase distorting part (AM/PM). The phase distorting part includes broadband biasing means and a non-linear transmission line that responds to these means. The biasing means are designed to bias the non-linear transmission line to a substantially phase distorting area. The characteristics of the circuit can be modified by adjusting a biasing voltage or by switching some of the diodes inactive through activation signals. The amplitude distorting part and the phase distorting part can be similar in structure, but the diodes are partly forward-biased, which reduces the amplitude losses caused by them.
