摘要： An RF quasi circulator circuit is described herein. In accordance with one example of the disclosure the circuit includes a receive port, a transmit port and an antenna port as well as a differential amplifier stage having a first input, a second input and an output that is coupled to the receive port. The circuit further includes a first phase shifting element and a second phase shifting element.

摘要： A wideband communication system and method for wideband communication that provide plural signals to a single transmitting antenna. Each signal is independently modulated and amplified, and then combined with other signals for transmission on the antenna. The independent amplification, that is, amplification without prior combination with other signals, reduces the number of intermodulation products (IP), thereby reducing the need for complicated IP cancellation techniques. A distribution circuit provides that when the number of signals exceeds the number of amplifiers, two signals may be combined before amplification. The amplified signals may be combined before transmission in combiners that include transformers that reduce IP caused by RF interference. The transformers are formed by enclosing the transmission line within a cavity in a block of ferrite material.

摘要： Input power is applied to an input inductor/capacitor combination. The gates of each of two FETs are connected to the other side of the input inductor. The source of each FET is connected to ground potential. The drain of the first FET is connected to a first output port, and the drain of the second FET is connected to a second output port. A signal input on the drain of one of the FETs is 180.degree. out of phase with the same signal passing through the two FETs to the drain of the other FET. The gate and drain of the first and second FETs have series-connected resistance/inductance feedback networks to give input and output match. A series-connected isolation resistor and inductor are connected between the first and second output ports for feeding signals of reduced amplitude to offset signal feedback through the FETs.
