Abstract: A 180.degree. hybrid receptive of a fundamental frequency signal which may be adjusted over a range of frequencies produces the fundamental frequency signal at two output ports phased 180.degree. apart. Each of the output ports is coupled to a non-linear active device which produces the fundamental frequency and odd and even harmonics thereof. A 180.degree. and 0.degree. hybrid is coupled to receive at respective input ports the signal from the active devices and to produce at one output port all the odd harmonics and to produce at the other output port all of the even harmonics of the fundamental frequency. The even and odd harmonics of the fundamental frequency appearing at the two output ports of the 0.degree. and 180.degree. hybrid are isolated from one another.

Abstract: A variable-gain, constant output power amplifier which generates an output rf signal of constant power level in response to an input rf signal of varying power level. The amplifier gain is preadjusted by a plurality of feedforward automatic-gain-control circuits to provide the constant output power. The amplifier comprises five dual-gate MESFET signal-amplifying stages. The first and last stages do not have built-in automatic-gain-control. The first stage is provided for preamplification prior to sampling the input signal, and the last stage is provided for setting the level of the output power externally. The signal at the input of each of the middle three stages is sampled through a coupler and detected and processed at video frequencies to dynamically preadjust the gain of the next signal-amplifying stage.

Abstract: A 0.degree. and 180.degree. hybrid power divider/combiner includes a first quadrature hybrid and two other quadrature hybrids arranged in tandem with one output port of the first hybrid connected to an input port of the tandem arrangement and the other output port thereof connected to a delay of electrical length equal to that of the tandem arrangement. When an input signal is applied to one input port of the first hybrid with the other port terminated, two signals of reduced amplitude which are either in phase or of opposed phase (dependent on which input port receives the input signal) are produced at the output of the tandem arrangement and delay.

Abstract: Methods and systems are provided for global server load balancing in a communication network using a global site selector and an application control engine in communication with the global site selector, in which the application control engine notifies the global site selector in response to a state change for a virtual internet protocol (VIP) address. Keepalive methods generally rely on periodically polling VIP addresses to check whether they are in an ONLINE or OFFLINE state. A minimum interval between two keepalives can be as long as 40 seconds, during which, without a mechanism to reflect state change to the load balancer in real time, if a VIP address changes state (e.g., VIP address failure), a customer can experience network outage during the time interval. Embodiments provide a mechanism to reflect, in real time, the current VIP address state to a global server load balancer to reduce failure detection time.
