ADF4351 Signal Source VFO Variable-Frequency Oscillator Signal Generator 35MHz to 4000MHz Digital LC

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: PCB Color: green Power 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 range Standby current: < 25mA Emission current: < 150mA Output impedance: 50 ohms Output frequency range: 35MHz-4000MHz Output step: 1KHz-8KHz Output power: -1dBm(W)@150MHz (test power absolute value) approx. 1mW Item size: 80 * 75 * 30mm / 3.1 * 3.0 * 1.2in Item weight: 85g / 3.0ounce Package size: 118 * 97 * 35mm / 4.6 * 3.8 * 1.4in Package weight: 108g / 3.8ounce ? Note:
? This product operation keyboard has 15 ppt keys, 0~9 number keys, 10, ++? and -- keys adjust the frequency to use, and also generate emission output behavior. Press the ++ or -- key to add 1KHz or lose 1KHz to the primitive frequency output. Press and hold ++ or -- for more than 1 second, continuous or continuous reduction will occur. The scanning mode is 1KHz at 35MHz~138MHz; 10KHz at 138MHz~550MHz; 100KHz at 550MHz~4000MHz. To end the scan, simply press the ++ -- button or the OK button. The OK button is the output control button. Click to launch, and press again to stop the transmission. The launch behavior caused by ++ or -- requires two OKs to end the launch behavior. This product is on the upper right of the display when there is output emission behavior. The corner will appear >>, the C button will end the emission and the frequency will be zero. ? Package Included: ? 1 x ADF4351 Signal Source VFO Signal Generator
