Abstract :
In most receivers a balanced mixer is used, while the output of the LNA is single ended. The presented phase splitter generates an accurately balanced signal out of a single-ended source. The wide-band circuit consists of two RF transistors and a DC control loop. The circuit operates up to, say, fT/4. In the article the basic circuit is discussed and an IC implementation is given.
