1. Module characteristics:
1, ADF4350/ADF4531 module is a senior engineer to build, fully refer to the official version of the design; PCB appearance, layout and design is reasonable, material attention;
2, output frequency range: 138M-4.4G (ADF4350), 35M-4.4G (ADF4351);
3, module can be controlled: control RF output switch and control output power;
4, key function: 1, FSK (the fastest processing signal 10mS); 2, switch RF output; 3, key frequency sweep frequency (single sweep frequency); 4, sweep frequency control (cycle sweep frequency);
5, power supply mode: 5V power supply, can be directly powered by USB;
6, color screen display, touch screen operation, can realize point frequency, sweep frequency, (special prompt: suggestion do not tear off the protective film on display screen, because touch screen is resistance screen, scraping will cause touch function failure).

3, provide: schematic diagram (PDF), provide the underlying driver of ADF4350/ADF4351 (do not provide source program of the project), other data;
Five. The introduction of the chip:
When ADF4350/ADF4351 is combined with external loop filter and external reference frequency, the fractional N frequency divider or integer N phase locked loop (PLL) frequency synthesizer can be realized.
The ADF4350/ADF4351 has an integrated voltage controlled oscillator (VCO) whose fundamental frequency range is 2200 MHz to 4400 MHz. In addition, using the 1/2/4/8/16 frequency divider circuit, the user can generate RF output frequency as low as 35Mhz/137.5 MHz. For applications requiring isolation, the RF output stage can be mute. The mute function can be controlled either by pin or by software. At the same time, it provides auxiliary RF output and can be turned off without using it.
