A method and/or apparatus for tuning a frequency synthesizer device toward a prescribed frequency may input a signal into the input of the frequency synthesizer to produce an output signal having an output frequency, select a first one of a set of the above noted prescribed coarse curves, and compare the magnitude of the difference between the prescribed frequency and the output frequency. Next, the method selects a second of the set of coarse curves as a function of the magnitude of the difference between the prescribed frequency and the output frequency. Preferably, the method selects the second of the set of coarse curves by selecting one or more of the coarse curves out of the sequential frequency order as a function of the magnitude of the difference between the prescribed frequency and the output frequency.

A phased antenna array system is provided that includes a beamforming integrated circuit and beamforming elements in communication with the integrated circuit disposed on a substrate. The beamforming integrated circuit includes multiple radio frequency (RF) signal ports. One or more of the RF signal ports includes an RF signal pad disposed between an edge of the integrated circuit and an internal RF ground pad. The RF signal pad and the internal RF ground pad of the RF signal port are oriented perpendicular with respect to the edge of the integrated circuit. Specifically, the RF signal pad has a first side disposed on or adjacent to the edge of the integrated circuit and an opposing second side that is adjacent to the internal RF ground pad. A method of controlling the phased antenna array system is also provided.

A system and a method for calibrating an antenna using trim bits and non-volatile memory is disclosed. In one aspect, an apparatus includes a power amplifier configured to at least amplify the output signal of the first antenna. The power amplifier includes multiple stages. The apparatus further includes a trim control circuit configured to adjust a bias of one of the stages of the power amplifier, using trim bits from non-volatile memory. The trim control circuit is further configured to scale the bias of one of the plurality of stages of the power amplifier by an integer between 0 and 2&#x2212;1 corresponding to a binary number formed by the first plurality of trim bits, wherein n corresponds to the number of trim bits.
