Abstract: Techniques for improved low latency frequency switching are disclosed. In one embodiment, a controller receives a frequency switch command and generates a frequency switch signal at a time determined in accordance with a system timer. In another embodiment, gain calibration is initiated subsequent to the frequency switch signal delayed by the expected frequency synthesizer settling time. In yet another embodiment, DC cancellation control and gain control are iterated to perform gain calibration, with signaling to control the iterations without need for processor intervention. Various other embodiments are also presented. Aspects of the embodiments disclosed may yield the benefit of reducing latency during frequency switching, allowing for increased measurements at alternate frequencies, reduced time spent on alternate frequencies, and the capacity and throughput improvements that follow from minimization of disruption of an active communication session and improved neighbor selection.

Abstract: An antenna adapter for interfacing a portable radiotelephone with external equipment. In a preferred embodiment, a connector assembly includes a first connector portion that inserts directly into the radiotelephone's antenna port, replacing the normal antenna assembly. Matching electrical components on a circuit board are used to match the impedance of the antenna port of the portable radiotelephone. A second connector portion typically uses conventional RF connectors to couple the radiotelephone antenna port to external equipment.

Abstract: A system and method for generating a local oscillator (LO) frequency in a ze ro intermediate frequency (IF) receiver or transmitter is presented. A signal i s received from a voltage controlled oscillator (VCO). The signal has a VCO frequency. The VCO frequency is divided by a number N to produce a signal having a divided-down frequency. The signal having the VCO frequency is then mixed with the signal having the divided-down frequency to produce an output signal having an output frequency. Local oscillator leakage is reduced. Thus , the receiver or transmitter may operate in multiple wireless communication bands and modes and meet the associated specifications.

Abstract: A dual-band antenna coupler for use in an adapter for portable radiotelephone. A plurality of curved bands of metal are positioned on a ground plane, with at least two of the plurality of curved bands of metal being electrically isolated from the ground plane so as to couple radio frequency (RF) signals to and from the antenna of the portable radiotelephone. The isolated curved bands of metal couple RF signals between the antenna of the portable radiotelephone and first and second matching circuits designed to match the portable radiotelephone antenna at each of the respective frequency bands. A selector switch coupled to the output of the matching circuits selects the appropriate matching circuit output for connection to an external antenna. The adapter also includes at least one ground pin mounted on the ground plane. When the portable radiotelephone is interfaced with the antenna coupler, the ground pin makes electrical contact with a ground reference connection on the portable radiotelephone.

Abstract: An antenna adapter (100) for interfacing a portable radiotelephone (200) with external equipment. In a preferred embodiment, a connector assembly (404) includes a first connector portion (406) that inserts directly into the radiotelephone's antenna port, replacing the normal antenna assembly. Matching electrical components (410) on a circuit board (400) are used to match the impedance of the antenna port of the portable radiotelephone. A second connector portion (408) typically uses conventional RF connectors to couple the radiotelephone antenna port to external equipment.

Abstract: A novel and improved dual band antenna system (100) comprising an inner antenna element (102) surrounded by an outer antenna element (104). In a first embodiment, the inner antenna element (102) radiates and receives RF signals in a first RF band, and the outer antenna element (104) radiates and receives RF signals in a second RF band. Optionally, the inner and outer antennas may be coupled together when operating in the first RF band in order to improve the antenna gain pattern of the dual band antenna (100). In a second embodiment, the inner antenna element (102) radiates and receives RF signals in both the first and second RF bands. In this second embodiment, when operating in the second RF band, the outer antenna element (104) is a grounded, thus altering the signal length of the inner antenna element (102) to resonate in the second RF band.

Abstract: A novel and improved antenna adapter for interfacing a portable radiotelephone 200 with test equipment is disclosed. In a preferred embodiment, the adapter assembly comprises an RF connector 104 at one end of an elongated conductor 102 which connects directly to the radiotelephone's 200 antenna port, replacing the normal antenna assembly. The elongated conductor 102 makes electrical contact with an external ground 204 of the battery charging ports at the bottom of the radiotelephone 200 at another end. The RF connector 104 may be impedance-matched to minimize RF signal attenuation when connected to the RF test equipment. In an exemplary embodiment, the RF connector 104 comprises a 50 OMEGA impedance-matched SMA connector.

Abstract: Techniques for improved low latency frequency switching are disclosed. In one embodiment, a controller (510) receives a frequency switch command and generates a frequency switch signal at a time determined in accordance with a system timer (520). In another embodiment, gain calibration is initiated subsequent to the frequency switch signal delayed by the expected frequency synthesizer settling time. In yet another embodiment, DC cancellation control (540) and gain control (530) are iterated to perform gain calibration, with signaling to control the iterations without need for processor (550) intervention. Various other embodiments are also presented. Aspects of the embodiments disclosed may yield the benefit of reducing latency during frequency switching, allowing for increased measurements at alternate frequencies, reduced time spent on alternate frequencies, and the capacity and throughput improvements that follow from minimization of disruption of an active communication session and improved neighbor selection.
