Especially an integrated VCO phase-locked loop of ADF4351 series with high performance-price ratio, which is convenient for developers to develop and use for the second time. It has a great in parameter design and test.The ADF4351 has an integrated voltage controlled oscillator (VCO) with a fundamental output frequency range of 2200 MHz to 4400 MHz. In addition, with 1/2/4/8/16/32/64 crossover circuits, users can generate RF output frequencies as low as 35 MHz.For applications requiring isolation, the RF output stage can be . The mute function can be controlled by pins or software. At the same time provide auxiliary RF output, and can be turned off when not in use.The ADF4351 is used in conjunction with an external loop filter and external reference frequency to implement an integer-N frequency-locked loop (PLL) frequency synthesizer.Module parametersModule model: ADF4351Module type: broadband PLL frequency sourcePower supply voltage: DC-5VModule current: 160mA (MAX); quiescent current 20mA (TYP) normal drive current (155mA)Module communication protocol: SPIModule provides routines: STM32F103RBT6; point frequency, frequency sweepRoutine platform: STM32F103X-M3; KEIL5 version source codeModule reference frequency: 100MHz; clock can be input externallyReference frequency signal amplitude: 700mVpp(MIN)Frequency stability: 25PPMPhase noise: different frequency phase noiseModule output frequency range: 35MHz-4.4GHzFrequency control step: 0.1MHzFrequency sweep step time: 1mS(MIN)Module output power: 7dBm (MAX); different frequency output power is differentModule output interface: SMA; 24-hour salt Module output signal: sine wave or square waveModule output channel: 2 differential channelsModule output impedance: 50 ohm matchingSignal characteristics of the module: 35MHZ--2.2GHz square wave (fundamental frequency division) 2.2GHZ--4.4GHz sine wave (fundamental wave)Module features: ultra-low phase noise, broadband RF PLL signal generatorModule working temperature: 0-75; civil gradeMaterial: PC+Metalcolour: As shownPackage Contents:1 x ADF4351 Phase-Locked Loop ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
