摘要： An ultra wide band-pass, absorptive band-reject filter has a pair of quadrature hybrid couplers cascaded and coupled by a phase shifting element and a matched pair of band-reject filters in two parallel paths. The matched pair of band-reject filters each rejects signals in a desired reject frequency band. The quadrature hybrid couplers each have an insertion loss amplitude crossover for signals propagated to terminals across the coupler that coincides with the reject frequency band. The phase shifting element is configured to have a phase shift of 180 degrees at frequencies in the reject frequency band. In a preferred embodiment, the pair of quadrature hybrid couplers are identical in performance and the band-reject filters are identical in performance with respect to a center frequency fn of the reject frequency band. The absorptive band-reject filter thereby provides an absorptive rejection response in the reject frequency band while a very wide pass-band frequency range is maintained.

摘要： A wide bandwidth, high power amplifier system for amplifying a signal in a radio frequency (RF) system in a specific bandwidth within the frequency range from 1 MHz to 100 GHz. The system includes a number of amplifier modules and an equal number of input transformers connected in series, with each input transformer providing an input signal to one amplifier module. It also includes an equal number of output transformers connected in series with each output transformer receiving an input signal from one amplifier module. The series of input transformers, the series of output transformers and the amplifier modules each provide an impedance matched approximately to the impedance of the RF system.

摘要： A radio link with two communicating transceivers each having a system for isolating incoming and outgoing radio signals to permit simultaneous transmit and receive by each transceiver on the same frequency or in the same frequency range. This is done so that in-coming receive signals received by each of the transceivers from the other transceiver is much stronger than the portion of its own transmitted signal that is coupled back into its antenna. The invention uses a special electronic circuit, termed the iso-circulator, to couple the antenna to both the co-located receiver and the transmitter. The iso-circulator circuit includes a simulated antenna load with an impedance matched to the antenna impedance. The circuit also includes a transformer with its primary side fed asymmetrically by the antenna so that it can pass the desired receive signal with minimum attenuation. The transformer's primary is on the other hand fed symmetrically from both sides by equally small portions of the transmit power from the co-site transmitter, but these signals are 180 degrees out of phase and cancel almost completely in the transformer.

摘要： A multi-coupler system for isolating radio signals in a transceiver, that includes a transmitter and a receiver, to permit simultaneous transmit by the transmitter and receive by the receiver through a single antenna in the exact same or nearby frequency ranges. This is done so that in-coming receive signals, transmitted from a remotely located radio, being detected by the receiver is much stronger than the portion of the transmit signal unintentionally coupled over by the co-site (or co-located) transmitter. The invention uses a special electronic circuit, termed the quasi-circulator, to couple the antenna to both the co-located receiver and the transmitter. The invention can also be used to couple several transceivers to a single antenna. The quasi-circulator circuit includes a simulated antenna load with an impedance matched to the antenna impedance. The circuit also includes a transformer with its primary side fed asymmetrically by the antenna so that it can pass the desired receive signal with minimum attenuation. The transformer's primary is on the other hand fed symmetrically from both sides by equally small portions of the transmit power from the co-site transmitter, but these signals are 180 degrees out of phase and cancel almost completely in the transformer.
