Abstract: In a TDM/TDMA portable radio communications system (5), a portable handset (201) is compatible for operation in FDD mode and TDD mode. In the FDD mode, different frequencies are used to separate a downlink transmission to a portable (201) from a port (204) from an uplink transmission from a port (204) to a portable (201). In the TDD mode, uplink and downlink transmissions are separated in different time-slots, but at the same frequency. The handset (201) includes common transmit and receive circuitry (300) that operates at fixed IF frequencies separated by the fixed FDD frequency difference between corresponding uplink and downlink signals. In the FDD mode, afrequency synthesizer (301), which is used to tune to transmit and receive at different frequencies from different ports, is not switched in frequency between transmitting and receiving a burst to and from a single port. In the TDD mode, the synthesizer (301) is switched in frequency between transmitting uplink and receiving downlink even though uplink and downlink signals are at the same frequency.

Abstract: A process of establishing valid sta-tistical dimensional tolerance limits for de-signs of detail parts that will enable accurate prediction of an economically acceptable degree of non-conformance of a large flexi-ble end item assembly, having a set of pre-determined dimensional tolerances, made from the detail parts, wherein the detail part tolerances are enlarged substantially com-pared to tolerances that would be necessary using an arithmetic "worst case" approach to remain within the end assembly toler-ances while remaining within preestablished stress limits of the parts. A preferred assem-bly sequence for assembling the parts into the assembly is selected and validated. Lo-cations, numbers arid size of coordination features to be machined in said detail parts are selected, by which the parts are located relative to each other and fastened together to form the assembly. Individual part statis-tical dimensional tolerances are established as a fabrication requirement for the parts that enable the parts to be economically produced and assembled into assemblies that meet the predetermined assembly dimensional toler-ances. The individual part statistical dimensional tolerances are broader than con~ ntional tolerances that are established to ensure acceptable assemblies when parts are assembled at the extremes of their tolerances. stac~  in a worst case manner. The parts are produced to the individual statistical dimensional tolerances in a capable process, having a Cpk ~ual to at least 1.0, while holding the mean values of the statistically determined dimensions of the individual parts to within a predetermined percentage of the nominal dimension. The end item is assembled in accordance with the preferred assembly sequence by locating the parts relative to each other by reference to the coordination features. The properly located parts art fastened together as located, using the coordination features as the primary determinator of assembly configuration.     configuration.
