An exemplary embodiment of an multiband antenna assembly includes a printed circuit board having a plurality of elements thereon. The plurality of elements may include a radiating element, a matching element, a feed element configured to be operable as a feeding point for the multiband antenna assembly, and a shorting element configured to be operable for electrically shorting the radiating element to ground. The antenna assembly may be operable within at least a first frequency range and a second frequency range different than the first frequency range without requiring any matching lump components coupled to the printed circuit board.

A circuit for controlling the output level of a power amplifier is disclosed. A current comparator (230) compares a reference current with a sensed current which is representative of the power amplifier current state. The reference current is used not only for comparison with the sensed current but also for setting the power amplifier (104). The current comparator (230) provides an output, based on the comparison, that is coupled to the power amplifier so that the power amplifier current is maintained at an optimum level for minimizing temperature dependent variations and substantially leveling the power of the power amplifier.
