Impact of Date Code Age Restrictions on Quality, Service, and Value
Extensive studies done by industry leaders, NASA and the U.S. military have shown substantial evidence that in modern storage environments, time intervals of five years or longer between manufacture of components and shipment to OEMs pose virtually no risk to the quality or reliability of electronic products.
Small Quantity Tape and Reel Splicing
Several years ago, Mini-Circuits CEO, Harvey Kaylie identified a void in the market: customers who were unable to justify purchasing a full-reel quantity of surface-mount components, but wanted smaller quantities packed for automated pick-and-place process.
High-Dynamic-Range MMIC Amplifier Supports CATV Upstream and Downstream Applications
Mini-Circuits' PGA-122-75+ 75Ω MMIC amplifier is designed and characterized for CATV applications with a frequency range of 40 to 1500 MHz, making it suitable for use in the downstream path.
Modulators: Introduction & Measurement Schemes
Mini-Circuits offers QPSK (quadrature phase-shift keying) and I&Q modulators from 10% bandwidth to as much as 5:1 octave span. So there's no longer any need to gather double-balanced mixers and 0° and 90° hybrids to assemble "in-house" QPSK or l&Q modulators.
Frequently Asked Questions About QPSK Modulators & I&Q Modulators and Demodulators
read through frequently asked questions about QPSK and I&Q Modulators and Demodulators informing on general use and specific applications.
Advantages of Cascading Reflectionless Filters
Cascading filters in series is commonly used to enhance stop-band rejection and steepness in the transition band. This can introduce problems in the pass-band such as ripple and phase instability, which distort the desired signal and degrade system performance.
Measurement Methods
The treatment given here is introductory, and will assist the reader who wishes to consult the standard texts for further detail on measurement techniques. For measurements on mixers and frequency doublers, please refer to the application notes on these subjects.
Coupler Theoretical Main-Line Loss Calculation (AN-30-004)
The main-line loss of a coupler is defined as the loss between the input and output ports. This articles derives the formula for conversion between the fraction of the input power that is outputted at the coupled port.
Pairing Mixers with Reflectionless Filters to Improve System Performance
Traditional filter designs employ circuits which reject undesired signals by reflecting them back to the source. There are many applications in which these reflections produce intermodulation products, gain ripples and other problems in system performance.
Handling of Mini-Circuits Open Case Models
Open case models require certain additional handling precautions. Following these precautions will ensure handling does not have a negative impact on the performance of the devices.
Electronic Attenuators
A useful feature of Mini-Circuits' electronic attenuators is the ability for either a positive or negative control current to provide the same amount of attenuation between input and output; this makes it useful for biphase modulation applications.
Directional Couplers
The directional couplers offered by Mini-Circuits are designed for both commercial and military applications. All models are available in plug-in, flat-pack, surface mount, and connectorized SMA, BNC, Type N, TNC (option) packages.
