Voltage and Current Regulated Power Supply

Here is a Simple Voltage and Current Regulated Power Supply using the LM723 IC. With the Values Shown, It is Adjustable from 3 to 30 Volts and 0 to 3 Amps. This circuit does NOT have Output SHORT CIRCUIT Protection, So a 3 Amp Fuse on the Output would be a Good Idea. Ideally you will put an Amp-Meter,

RF and Microwave Measurements

Microwave networks are harder to analyze than their lower-frequency counterparts. The reason is that the size of a typical microwave circuit is comparable the wavelength, so phase variation along a portion of the circuit cannot be ignored as is the case at lower frequencies.
