    摘要: An RF transmitter comprises a digital-to-IF circuit block configured to receive a digital in-phase baseband signal and a digital quadrature baseband signal and to up-convert the digital in-phase and quadrature baseband signals to a digital in-phase IF signal and to a digital quadrature IF signal. The wireless RF transmitter further comprises an IF-to-RF circuit block configured to convert the digital in-phase and quadrature IF signals to analog signals and to up-convert the analog in-phase and quadrature IF signals to an RF output signal. The digital-to-IF circuit block comprises pre-compensation circuitry configured to reduce analog impairments associated with the IF-to-RF circuit block.

    摘要: A system and method integrates signal filters in a multiband transceiver. A preferred embodiment comprises an amplifier with a first tunable capacitor coupled to a signal input and a tunable filter. The tunable filter comprises an input stage with a first pair of inductors arranged in a dipole configuration and a second tunable capacitor coupled in parallel to the first pair of inductors and an output stage inductively coupled to the input stage, the output stage includes a second pair of inductors also arranged in a dipole configuration and a third tunable capacitor coupled in parallel to the second pair of inductors. The inductors are realized using bond wire or any other high Q material. The first tunable capacitor, the second tunable capacitor, and the third tunable capacitor can be tuned using a master-slave tuning configuration to adjust the operating frequency of the amplifier and the tunable filter to enable frequency band compatibility with multiple communications protocols.

    摘要: Systems, methods and instrumentalities are disclosed for Doherty amplifier optimization. Amplifier configurability and control therefore may be integrated. Amplitude alignment, phase alignment, amplifier gate biasing, driver gate biasing and temperature compensation for N paths in Doherty configurations may be integrated, for example, using a programmable LUT storing control bit patterns. Configurability may comprise reconfigurability between asymmetric power split ratios, between symmetric and asymmetric relationships and between classic and inverted phase relationships, permitting path reconfigurability for higher or lower power and leading or lagging phase. Multiple versions providing more or less configurability and/or control range with more or less insertion loss, such as design and production versions, may be pin compatible, e.g., to reduce time and expense for R&D and production transition. Integration of configurability and/or control may reduce complexity in design, development, control, optimization, production and application, e.g., by eliminating interfaces, mismatches or excessive capacitance between discrete chips.

    摘要: Disclosed are wirebonding methods wherein bondwires are positioned using dynamically determined variations in die placement. Preferred methods of the invention include steps for placing a die on the prepared substrate using selected ideal placement coordinates. Deviation of the actual die placement from the selected ideal placement coordinates is monitored, and one ore more critical bondwires are wirebonded between respective die pins and pins on the substrate. The monitored placement deviation is used to dynamically position the critical bondwires on the critical pins according to actual die placement. Disclosed embodiments include methods using lateral deviation monitoring and angular deviation monitoring to dynamically position bondwires.
