Phantom RF Dummy Load 10 Watts circuit Diagram



Phantom RF Load 10 Watts circuit Diagram


The circuit above is a dummy load capable of handling up to 10 watts of RF power for a few minutes, and its impedance is 50 ohms. It is constructed with 10 parallel resistors 560 ohms per 1 watt, R1 to R10, a voltage divider R11-R12 and a rectifier D1-C1. Its output voltage in a voltmeter which can be connected to measure the RF power.

Build a 12V 7.2Ah SMF Battery Charger Circuit Diagram . The LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5A over an output-voltage range of 1.25 V to 37 V. It is exceptionally easy to use and requires only two external resistors, R2’ and R2” (R2= R2’+ R2”) to set the output voltage. Furthermore, both line and load regulation is better than standard fixed regulators. In addition to having higher performance than fixed regulators, this device includes on-chip current limiting thermal overload protection, and safe-operating-area protection. All overload protection remains fully functional, even if the ADJUST terminal is disconnected. By connecting a fixed resistor, R1 the ADJUST and OUTPUT terminals, the LM317 can function as a precision current regulator. An optional output capacitor can be added to improve transient response. Schematic Diagram using LM317   The ADJUST terminal can be bypassed to achieve very high ripple-rejection ra

Full Power Mobile Phone Jammer Circuit Diagram .To day if we are talking about expert Cell phone Jammers we are conversing about this schematic underneath. First off all you should be very very cautious how to use this apparatus. Its completely illegal and so the reason. I post this Circuit is only for educational and testing causes. This type of apparatus is being utilised by security for VIPS, particularly at their limousines to avoid blasting device initiating while the vehicle passes from the goal cell phone-bomb. Off course there are those who use it to make a antic or to make the persons crazy in the rectangle block you are. The power of the jammer is currently sufficient to do your thing, but certainly you can place a 30W linear power amp at the RF output and impede a much wider locality. So, Be pleasant individual with that and recall that there are people who may need desperately to obtain or make a call and one of them could be you! And if you can't oppose of functio

On line Ladder Program Editing for RSLogix 500

On line Ladder Program Editing for RSLogix 500 There are five basic steps in performing an edit on line.   1)   Start Edits, 2)   Make Changes, 3)   Accept edits, 4)   Test Edits, and 5) Assemble edits.   Although these steps seem very simple there are a few rules to watch out for.   You cannot expand or create a data table on line in the SLC, and you must be in program mode (or off line) to expand a data table on line in the PLC-5.   You cannot make an on line edit if the key switch is in Run Mode.   In the PLC-5, if backplane switch 8 is on, you cannot make an on line edit.     You do not need to perform an on line edit to directly change a value in the data table such as the preset of a timer or counter.   If the processor is in program mode, you do not need to test and assemble after accepting.   If the processor is in program mode, and a rung is deleted, there is no warning. Let's walk through the 5 step procedure: Look at the rung below.   Our objective is to transfer contro
