摘要： An object of the present invention is to realize a loop through circuit, in an active connector, securely having a preferable mismatching attenuation characteristic and having a preferable signal transmission characteristic, with respect to an input port, an output port, and an internal port, without providing a special circuit outside the connector. A connector base part has the input port inputting an external signal, the output port outputting a loop through signal, and the internal port outputting a signal into a device. First and second matching circuits, an equalizer circuit, a dividing circuit, and a driving circuit are stored in the connector base part. The matching circuit is supplied with an external signal input from the input port. The dividing circuit divides a signal to be input to generate first and second divided signals, and outputs them to the internal port and the output port. The equalizer circuit compensates for a frequency characteristic and/or loss of a signal to be input. The driving circuit is provided between the dividing circuit and the matching circuit, and drives a transmission line to be coupled to the output port.

摘要： A variable capacitance cell includes a hybrid coupler including a first port, a second port, a third port, and a fourth port. A first variable capacitance is connected to the second port. The first variable capacitance includes one or more first variable micro-electromechanical system (MEMS) capacitor. A second variable capacitance is connected to the third port. The second variable capacitance includes one or more second variable MEMS capacitors. Control signals are applied to the first and second variable capacitances to selectively change the capacitances of the first and second variable capacitances, thereby modifying a phase difference between a signal input at the first port and a signal output from the fourth port.

摘要： A power combiner has at least two uncommon ports and at least one common port. Isolation between the uncommon ports over a broad band is achieved through a lossy band response circuit having a phase and amplitude response effective to compensate for changes in phase and amplitude between the uncommon ports with change in frequency of an input signal. The lossy band response circuit may have a resistance approximating a resistance effective to isolate the uncommon ports over a bandwidth at a center frequency. A coupler may likewise increase the band for which an input port is isolated from the isolated port by coupling a lossy circuit between the input port and isolated port. The lossy circuit may be embodied as a lossy band response circuit.

摘要： A signal handler providing high linearity in a small size, applicable across wide operating frequencies and bandwidths, while also adapted to preferred integrated circuit (IC) and printed circuit board technologies. In one implementation, a signal handling apparatus includes an input impedance transformer for receiving an input signal and matching an internal apparatus impedance, a splitter for providing N split signals, a number of signal processing circuits for processing the N split signals, a combiner for combining the N split signals into a combined signal, and output impedance transformer for receiving the combined signal and for matching the internal apparatus impedance to an output impedance of the apparatus. The apparatus may provide filtering, duplexing and other radio frequency signal processing functions. A tunable duplexer may be implemented using a vector inductor and tunable capacitor array with frequency dependent impedance transformers.

摘要： The present disclosure relates to a reconfigurable directional coupler with a variable coupling factor that can be changed in value as a function of a desired transmit band of operation. The reconfigurable directional coupler includes a primary inductive segment, secondary inductive segments, and switch circuitry configured to change the total coupling capacitance formed between the primary and secondary inductive segments by selectively switching the secondary inductive segments into the secondary signal path. Simultaneously, the mutual inductance and coupling factor between the primary and the secondary inductive segments are reconfigured.
