However, as opposed to simply generating a random alternative content for the first communication, the system performs an additional step to ensure that the alternative content is specific to the provider and may be used across all access points for the provider. |

Firewall switchover with minimized session disconnection
A pseudo-active/active firewall configuration handles firewall switchover events with minimized session disconnection. A passive firewall is set to an active state, and an active firewall is switched to a pseudo-active state wherein it continues to process ingress and egress traffic according to traffic handling protocols for its active state. During updating of a corresponding Network Address Translation (NAT) table to route traffic to the now-active firewall, the pseudo-active firewall enters a forwarding state wherein it forwards ingress network sessions to the now-active firewall and processes the ingress network sessions according to its active state. The now-active firewall receives the ingress network sessions and records session states prior to discarding them. After updating the NAT table, when traffic is routed to the now-active firewall, the recorded session states are used to maintain active sessions. |

Systems and methods for PLL duty cycle calibration
To enhance phase-locked loop (PLL) performance, PLL duty-cycle calibration may be desirable. In some cases, higher reference clock frequency may assist in reducing phase noise and increasing power efficiency of the PLL. A frequency doubler may increase the PLL reference clock frequency, but the duty cycle error in the clock may result in a spur at a clock frequency offset.

Correcting for the static phase offset may cause a disturbance at the PLL output. To address the duty cycle error caused by the higher reference clock frequency, a duty cycle calibration loop may be introduced. For the duty cycle calibration loop, phase offset information may be extracted. |

Reactance cancelling radio frequency circuit array
A reactance cancelling radio frequency (RF) circuit array is disclosed. The reactance cancelling RF circuit array includes multiple RF circuits each coupled to one or two adjacent RF circuits by one or two pairs of coupling mediums each having a respective length less than one-quarter wavelength. In one aspect, an RF input signal is first split across the RF circuits and then combined to form an RF output signal. As a result, each RF circuit requires a lower power handling capability to process a portion of the RF input signal. In another aspect, each pair of the coupling mediums can cause reactance cancellation in each reactance-cancelling pair of the RF circuits. By coupling the RF circuits via the coupling mediums and enabling splitting-combining among the RF circuits, it is possible to miniaturize the reactance cancelling RF circuit array for improved performance across a wide frequency spectrum. |
