1.Simple RF signal source signal generator 2.Core component: avr mega8 microcontroller, cost-effective single chip, is a low-profile version of the commonly used m16. There is a 2.56v voltage regulator in the peripheral ADC, which other mid-range microcontrollers do not have. 3.Adf4351: Traditional VCO + PLL + 6 series high-speed bistable circuit. The output is obtained by frequency division, and the output is a square wave. The amplitude of the fundamental wave does not change much. 4.This product provides a signal source for the AC channel of the device under test and analyzes the frequency-amplitude characteristics of the AC channel. Please pay attention to the impedance of the measuring equipment. Power supply voltage: DC 4.5V-5.5V Standby current: Less than 25mA Transmit current: Less than 150mA Output impedance: 50 ohms Output frequency range: 35MHz-4400MHz Output step: 1KHz-8KHz Output power: -1dBm (W) 150MHZ (test power absolute value) about 1 mW Note: Installation guide not included, we strongly recommend you professional installation. Please check as much as possible to make sure the item is what you need. Tips: The product may be updated constantly ,Due To Different Batches, The Actual Product May Have Slight Differences Or Color Differences, Which Does Not Affect Use Color: As Shown Material: PCB Package Contents: 1 x RF signal generator module 1 cord 1 x antenna Only 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. The measurement allowed error is +/- 1-3cm.
