35MHz~4400MHz OLED Display RF Signal Generator ADF4351 Module Sweeps Frequency Generator PLL

Features:
The main control adopts STM32F103C8T6, fractional N divider frequency synthesizer and integer N divider frequency synthesizer PLL-ADF4351 PLL.
The output frequency ran-ge is 35MHz~4400MHz, the main board adopts four-layer gold precipitation process, finecomponent selection, classic layout and wiring printed circuit boarddesign, making the signal output extremely stable, phase noise to meet the official design requirements.
On-board 25MHz active SiTime crystal oscillator, and reserved external clock interface, MCU ADC interface. Simple five-key operation design, clear logic, can set the point frequency, sw-eep mode output, sw-eep frequency step and sw-eep cycle can be adjusted.
Programmable SiTime crystal oscillator, reserved for external clock.
Five-way navigation button, easy to operate, and with CH340C serial chip, serial communication and firmware download can be realized.
