Introducción
WF105RB is one low power direct-conversion OOK/ASK receiver. The circuit is mainly intended for the ISM (Industrial, Científico y médico) band 315/433MHz, it is designed for low cost data transmission
system for data rate less than 40Kb/s in Manchester.
WF105RB integrates most circuit components on-chip and only requires a few external components to work normally. The WF105RB consists of a low-noise amplifier (LNA), a down-conversion mixer, an onchip phase-locked loop (PLL) with integrated voltage-controlled oscillator (VCO) and loop filter, an ASK demodulator, a data filter, a data slicing comparator and an on-chip regulator.
The WF105RB is designed for low power and low voltage wireless applications. It is available in TSSOP-16 package and working over the extended temperature range (-40 a +85 ° C).
