ABSTRACT:
Disclosed is a 90-degree phase splitter utilized in QPSK modulator and demodulator. The 90-degree phase splitter uses a transistor thereby converting a voltage source into a current source, and accordingly obtains two outputs having same in magnitude but different in phase by 90 degrees through output circuits comprising reactors and resistors.
