Applicant: Shen Zhen JWL Electronic Co., Ltd. FCC ID: PVDPDWM-2600 Operational Description 1. Audio 1) MIC AMP(N1) This amplifiers the voice signal of 50Hz~15KHz by about 20dB and makes pre-emphasis features of 50us. 2) Regulator (N2) This makes standard voltage for MIC AMP and RF part being supplied power from 9V Battery. 2. RF 1) Oscillator (VT3) This is a transmitting carrier oscillator that modulates the voice signal supplied for Audio to frequency and then oscillates third-time overtone and becomes standard oscillation for RF Carrier. 2) MULTI (VT4) This multiplies the frequency oscillated from VT3(FREQ: 2 multiplied frequency) 3) MULTI (VT5) This also multiplies the frequency multiplied in VT4.(FREQ: 2 multiplied frequency) 4) Buffer This doesn’t make the antenna affect the internal circuit when connecting the antenna and final carrier multiplied from VT6.
