Abstract: Un aparato (110), que comprende: un filtro de banda estrecho (544) para una primera banda de frecuencia y que tiene un primer ancho de banda más estrecho que la primera banda de frecuencia, estando configurado el filtro de banda estrecho para recibir y filtrar una señal de radiofrecuencia (RF) de entrada y proporcionar una señal de RF filtrada; y un amplificador de potencia (550) que tiene una entrada acoplada operativamente a una salida del filtro de banda estrecho, estando configurado el amplificador de potencia para recibir y amplificar la señal de RF filtrada y proporcionar una señal de RF amplificada; un primer trayecto de señal que comprende el filtro de banda estrecho (544) y acoplado a la entrada del amplificador de potencia (550) mediante un primer conmutador (548a); y un trayecto de señal de desvío (546) acoplado a la entrada del amplificador de potencia mediante un segundo conmutador (548b); en donde, cuando el aparato se comunica simultáneamente con una primera red inalámbrica (120) en la primera banda de frecuencia y con una segunda red inalámbrica (130) en una segunda banda de frecuencia adyacente a la primera banda de frecuencia, el primer trayecto de señal se conecta al amplificador de potencia de tal manera que se seleccione el filtro de banda estrecho, y cuando no hay ninguna comunicación simultánea con las dos bandas de frecuencia, el filtro de banda estrecho se omite.

Abstract: A local oscillator includes a programmable frequency divider coupled to the output of a VCO. The frequency divider can be set to frequency divide by three. Regardless of the divisor, the frequency divider outputs quadrature signals (I, Q) that differ from each other in phase by ninety degrees. To divide by three, the frequency divider includes a divide-by-three frequency divider. The divide-by-three frequency divider includes a divide-by-three circuit, a delay circuit, and a feedback circuit. The divide-by-three circuit frequency divides a signal from the VCO and generates therefrom three signals C, A' and B that differ from each other in phase by one hundred twenty degrees. The delay circuit delays signal A' to generate a delayed version A of the signal A'. The feedback circuit controls the delay circuit such that the delayed version A (I) is ninety degrees out of phase with respect to the signal C (Q).

CPC classification number: H03K3/017 , H03K5/1565
Abstract: Techniques are disclosed for adjusting and programming the duty cycle of a signal generated by a circuit. In an embodiment, parallel transistors are coupled between a NAND gate and a supply voltage. Selectively enabling the parallel transistors adjusts the switching point of the NAND gate, thereby allowing control of the pulse width of the output signal. In an alternative embodiment, the size of the PMOS versus the NMOS transistors in the NAND gate is selectively varied to achieve the same effect. Further disclosed are applications of the techniques to calibrating the receiver to minimize measured second-order inter-modulation products and/or residual sideband.

Abstract: Techniques are provided for reducing mismatch between the in-phase (I) and quadrature (Q) channels of a communications transmitter or receiver. In an exemplary embodiment, separate voltages are applied to bias the gates or bulks of the transistors in a mixer of the I channel versus a mixer of the Q channel. In another exemplary embodiment, separate voltages are applied to bias the common-mode reference voltage of a transimpedance amplifier associated with each channel. Techniques are further provided for deriving bias voltages to minimize a measured residual sideband in a received or transmitted signal, or to optimize other parameters of the received or transmitted signal. Techniques for generating separate bias voltages using a bidirectional and unidirectional current digital-to-analog converter (DAC) are also disclosed.
