Abstract: In a broadband communication system there are multi-stage power amplifier systems for amplifying the power of radio-frequency (RF) communication signals. Each stage of the amplifier system results in composite triple beat (CTB) distortion, and if the phase of the CTB distortions are approximately the same (i.e. are in-phase), then the amplitudes of the distortions are added (i.e. “20 dB” rule). The amplifier system of the invention includes one or more phase filters positioned in series between the power amplifier stages. The phase filters are adapted to shift the phase of the communication signals, so that the phase of CTB distortions, resulting from the amplification of the communication signals in the amplifier stages between the phase filters, are substantially different (i.e. are out-of-phase). Thus, only the power of the CTB distortions are added (i.e. “10 dB” rule).

Abstract: A circuit and method for creating an all pass network for equalizing the group delay of a filter. The all pass filter provides an equalization network including a transformer having a primary and secondary winding magnetically coupled together. One end of each primary and secondary winding is connected together to form a connection, the remaining ends of the primary and secondary winding constitute input and output terminals to the equalization network. Control over the group delay response is effected by a bias conductor serially connected to the common ends of the primary and secondary winding and a capacitor connected to the common terminal. The bias conductor modifies the mutual inductance, therefore modifying the coupling factor for the transformer. By shifting control of the coupling to the bias conductor, group delay response may be controlled without further modifications of the transformer coupling.

Abstract: To make a variable phase shifter at low cost and that is easy to manufacture, two propagation paths for a high frequency signal are provided in parallel between the input and the output of the phase shifter. These two paths are of different lengths. An intermediate node on one of the paths is connected to an intermediate node on the other path by a PIN diode. The diode is connected to the paths by a segment of line further enhancing the length difference. By biasing the diode to a desired level, it is caused to present a particular impedance to propagation. It is shown that by acting in this way the diode can vary the phase shift between the input and the output without needing to use harmful reactive components.

Abstract: A filter, for use with a delay compensating circuit in a delay line filter, formed from co-located capacitors. The capacitors may be formed as traces disposed on a circuit card and co-located to provide capacitive coupling to each other and ground. Proximity coupling wires are connected at one end to capacitive traces, and at the other end hang in mid-air above the next adjacent capacitive trace. The distance between each proximity coupling wire and the neighboring capacitive trace can be varied to control the capacitance coupling between neighboring capacitive traces. The filter is thus tuned by controlling the distances between the proximity coupling wires, and by squeezing or stretching the inductors. The shunt coils control the frequency of the filter, while the series of capacitive traces control the bandwidth.

The electrical cross connect circuits are spaced along the lengths of the two transmission lines, e.g., preferably to form evenly spaced distances therebetween. The total delay through the wide band electrical delay line is adjusted by selectively activating an appropriate one of the plurality of cross connect circuits between the two transmission lines.
