The Prevention and Control of Electrostatic Discharge (ESD)
We experience occurrences of static electricity everyday. While this sudden discharge of static electricity does not result in any harm to the human body, it can be very damaging to electronic devices which are sensitive to electrostatic discharge (ESD). This article is intended to instruct on the sources of ESD and preventative methods.
Automated Compression Measurements Using Network Analyzers
The dynamic range of an amplifier is determined by noise figure and compression. Since, conventional compression measurements are error prone and tedious, multi-channel and power sweep capabilities of modern network analyzers, can be used to perform automated compression measurements.
Stepped Frequency Measurement to Improve IM Testing
Low pass filters used in IM testing can be remotely controlled to reduce setup time and improve measurement accuracy.
The design example covered here is an 800 to 900 MHz synthesizer in 100 kHz steps with a minimum output power of 10 mW across the band. Mini-Circuits model POS-1060, a low noise voltage controlled oscillator that operates over the range of 750 to 1060 MHz, is used.
Reducing Power Supply Noise in VCOs
It is always a good design philosophy to provide RF bypassing of power and DC control lines to the VCO. This is indeed the case when the VCO is located some distance away from the power supply.
Constant-Impedance IF Band-pass Filters Improve Circuits Performance
Double-balanced mixers are normally very wideband. When used as down converters, the sum and difference of frequencies are of equal amplitude. Filtering is essential to remove the sum frequency.
Methodology for Computation of Maximum Power Handling in LTCC Low-Pass Filters
LFCW series filters are made using LTCC (low temperature co-fired ceramic) technology. Due to low losses and high temperature handling capability of the ceramic material, they can handle reasonably high power levels, even though they are of small size.
VCO Test Methods
Well regulated power supplies are recommended for tuning and VCO supplies. Bias tee's in the DC and tuning voltage lines help reduce the power supply noise. This article will cover information on tuning, harmonics and spurious level and more.
An Introduction to Filters
In the operation of electronic systems and circuits, the basic function of a filter is to selectively pass, by frequency, desired signals and to suppress undesired signals. The amount of insertion loss and phase shift encountered by a signal passing through the filter is a function of the filter design.
An Introduction to Frequency Multipliers
Mini-Circuits' frequency multipliers offer a new degree of freedom in designing frequency multiplier chains. Their multi-octave band width and excellent rejection of fundamental and third harmonics enable a significant reduction in filter requirements.
