摘要: A system and a method achieve a higher level of stable gain for a cellular telephone booster (repeater) than previously considered to be achievable. An RF signal booster includes active stability control provided by an active stability network. The active stability network decreases the amount of radiated or conducted parasitic signal coupled from the output of an amplifier back to the input of the amplifier. The active stability network allows a higher system gain than would otherwise be achievable. In one embodiment, the active stability network (stabilization network) includes an RF sample coupler, one or more band pass filters, a vector modulator, an RF recombining coupler and an RF detection circuit. An algorithm controls the stabilization network to minimize the amount of parasitic coupled signal from the output of the amplifier back to the input of the amplifier and to maximize the achievable system gain.

摘要: Wireless repeaters comprising antennae having high electrical isolation are presented. Multi-band antennae are placed on opposing sides of a conductive ground plane to achieve high electrical isolation, preferably higher than 30 dB. The antennae are preferably placed at a distanced from the ground plane that is less than 0.5 wavelengths of a frequency associated with frequency bands to which the antennae are responsive. The presented antennae system reduces the minimum amount of isolation required for stable operation.

摘要: A wireless repeater comprises dual cancellation loops. The wireless repeater includes an active cancellation loop and a passive cancellation loops. The active cancellation loops reduces an environmentally induced signal component from a receive signal entering the repeater's amplifier. The passive cancellation loop reduces leaked signal component from the received signal.
