- Reducción de la corriente de la batería usando TPS62730
- The TPS62730 [26] is a step down converter with bypass mode for
ultra low power wireless applications - In RX, the current drawn from a 3.6 V battery is typically less than
11 mA when TPS62730 output voltage is 2.1 V. When connecting CC1101
directly to a 3.6 V battery the current drawn is typically 17 mA - In TX, at maximum output power (+12 dBm), the current drawn from a
3.6 V battery is typically 22 mA when TPS62730 output voltage is 2.1 V.
When connecting CC1101 directly to a 3.6 V battery the current drawn is
typically 34 mA - When CC1101 enters SLEEP mode, the TPS62730 can be put
in bypass mode for very low power down current - The typical TPS62730 current consumption is 30 nA in bypass mode.

Descripción del CC1101
CC1101 es un transceptor sub-1 GHz de bajo costo diseñado para aplicaciones inalámbricas de muy baja potencia. El circuito está destinado principalmente a las bandas de frecuencia ISM (Industrial, Científico y Médico) y SRD (Dispositivo de Corto Rango) a 315, 433, 868 y 915 MHz, pero puede programarse fácilmente para funcionar en otras frecuencias en las bandas 300-348 MHz, 387-464 MHz y 779-928 MHz.
El transceptor de RF está integrado con un módem de banda base altamente configurable. El módem soporta varios formatos de modulación y tiene una velocidad de datos configurable de hasta 600 kbps.
CC1101 proporciona un amplio soporte de hardware para el manejo de paquetes, almacenamiento en búfer de datos, transmisiones de ráfagas, evaluación de canales claros, indicación de calidad de enlace y despertador por radio.
Los principales parámetros operativos y los FIFOs de transmisión/recepción de 64 bytes del CC1101 pueden controlarse a través de una interfaz SPI. En un sistema típico, el CC1101 se usará junto con un microcontrolador y unos pocos componentes pasivos adicionales.
El extensor de rango CC1190 850-950 MHz [21] se puede usar con CC1101 en aplicaciones de largo alcance para mejorar la sensibilidad y una mayor potencia de salida.
