摘要： An active quadrature power splitter having low power consumption is small in size and is inexpensive, for obtaining two output signals of which the phase difference is 90 degrees. Since the active quadrature power splitter operates as a microwave amplifier for obtaining two amplified microwave outputs having an equal magnitude and a phase difference of 90 degrees by using a matching circuit of the amplifier, a power gain can be obtained. Also, since a single FET or HBT is used and two output signals are generated in an output impedance matching circuit, the circuit becomes simplified. Therefore, the circuit can be easily implemented in a monolithic microwave IC and the chip size can be reduced.

摘要： A radio-frequency (rf) power combiner or divider structure containing distributed amplifier components and having broadband operating characteristics, and operable with net gain or practically no insertion losses. The divider structure includes an input transmission line having series-connected impedances that interconnect with active devices, such as field-effect transistors to form a practically lossless line. The active devices provide gain between distributed points in the input transmission line and distributed points in multiple output transmission lines, which are similarly structured as series-connected impedances. Each output transmission line supplies one of the divider outputs. In the combiner form of the device, there is a single output transmission line and multiple input transmission lines, coupled to the output line in a distributed manner by active devices.
