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: An apparatus and method for filtering a signal in a phase lock loop is disclosed. An typical apparatus for filtering a phase error signal comprises a first filter subcircuit receiving a phase error signal from a phase comparator and filtering the error signal when enabled, a second filter subcircuit receiving the phase error signal from the phase comparator and filtering the error signal when enabled and first and second enable switches which are activated in combination to control filtering of at the error signal. The first filter subcircuit is enabled by activating a first combination of the enable switches and the second filter subcircuit is enabled by activating a second combination of the enable switches. A fast acquisition subcircuit can also be used to temporarily underdampen the filter and improve overall performance of the phase lock loop circuit. The filter can be used to obtain multimode operation in a cellular radio.

Abstract: A system and method for generating a local oscillator (LO) frequency in a zero intermediate frequency (IF) receiver or transmitter is presented. A signal is 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: An antenna adapter (100) for interfacing a portable radiotelephone (200) wit h 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. Matchi ng 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 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.
