ADF4351-VFO Digital LCD Display RF Signal Source Signal Generator 35MHz-4000MHz

Description

ADF4351-VFO Digital LCD Display RF Signal Source Signal Generator 35MHz-4000MHz
Features:
Simple RF signal source signal generator.
Core components: avr mega8 microcontroller, cost-effective single-chip microcomputer, is the low-end general-purpose m16 version, the peripheral adc has a 2.56 v regulator supply, this is not available on other mid-range microcontrollers .
Adf4351, the traditional vco + pll + 6 series high speed bistable circuit (except 2 circuits, trigger d).
35-2200 mhz is obtained by frequency division. After being shaped, the amplitude of the fundamental wave does not change much. This is for high frequency.
(After the signal is split, 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, reduces development time, saves 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
Green color
Supply voltage: dc 4.5 v-5.5 v, please note that this machine has no built-in voltage regulator unit, it should not supply over the voltage range

Item size: 80 * 75 * 30mm / 3.1 * 3.0 * 1.2in
Item weight: 85g / 3.0 oz
Package size: 118 * 97 * 35mm / 4.6 * 3.8 * 1.4in
Package weight: 108g / 3.8 oz
Note:
This product operation keyboard has 15 ppt keys, 0 keys, 9 numeric keys, 10, "+ +" and "-" keys that adjust the frequency to use, and also generate emission output behavior.
Press the "+ +" or "-" key to add 1 kHz or lose 1 kHz for the primitive frequency output. Press and hold "+ +" or "-" for more than 1 second, continuous or continuous reduction will occur.
The scanning mode is 1 khz at 35 mhz ~ 138 mhz; 10 khz at 138 mhz ~ 550 mhz; 100 khz at 550 mhz ~ 4000 mhz.
To end the scan, simply press the "+ +" - "button or the" ok "button. The" ok "button is the exit control button. Click to launch and press again to stop the transmission.
The launch behavior caused by "+ +" or "-" requires two "ok" s to end the launch behavior. This product is in the upper right corner of the screen when there is output emission behavior.
The corner will appear ">>", button "c" will end the broadcast and the frequency will be zero.
