描述 Description

WF152RB is one low power direct-conversion FSK receiver. The circuit is mainly intended forthe ISM (Industrial, Scientific and Medical) band 315/433MHz, it is designed for low cost datatransmission system for data rate less than 40Kb/s.WF152RB integrates most circuit components on-chip and only requires a few externalcomponents to work normally. The WF152RB consists of a low-noise amplifier (LNA), adown-conversion mixer, an on-chip phase-locked loop (PLL) with integrated voltage-controlled oscillator (VCO) and loop filter, an FSK demodulator, a data filter, a data slicingcomparator and an on-chip regulator.WF152RB is designed for low power and low voltage wireless applications. It is available inSOP-8 package and working over the extended temperature range (-40 to +85°C).
