ADF4351 Signal Source VFO Variable-Frequency Oscillator Signal Generator 35MHz to 4000MHz Digital LCD Display USB DIY To

Features Simple RF signal source signal generator Core components avr mega8 microcontroller cost effective single chip microcomputer is commonly used m16 low version peripheral ADC has a 2 56V regulator source this is not available in other mid range microcontrollers Adf4351 the traditional VCO PLL 6 series high speed bistable circuit except 2 circuits D trigger 35 2200MHz is obtained by frequency division After being shaped the amplitude of the fundamental wave does not change much This is for high frequency DDS is difficult to achieve in full bandwidth after the signal is divided it must be a rectangular wave and the amplitude becomes the trigger level This product uses the single chip microcomputer as the core which greatly simplifies the design shortens the development time saves the cost and is simple reliable and practical Provide a signal source for the AC path of the device under test analyze the frequency amplitude characteristics of the AC path and pay attention to the impedance of the device under test Specifications Main material PCBColor greenPower supply voltage DC 4 5V 5 5V please note that this machine does not have built in voltage regulator unit must not supply over voltage rangeStandby current 25mAEmission current 150mAOutput impedance 50 ohmsOutput frequency range 35MHz 4000MHzOutput step 1KHz 8KHzOutput power 1dBm W 150MHz test power absolute value approx 1mWItem size 80 75 30mm 3 1 3 0 1 2inItem wei
