Webinar: IQ, Image Reject, and Single Sideband Mixers Demystified
May 28, 2020 | 8am PST

Quadrature mixers (IQ, Image Reject, and Single Sideband) are offer powerful capabilities and are critical to modern communication and electronic warfare systems. However, they are also among the most complex RF and Microwave circuits. In this webinar, Marki Microwave will deconstruct these powerful circuits by explaining:
• How ‘quadrature’ signals lead to signal cancellation without filtering
• Common compensation techniques for optimal carrier and sideband suppression
• The best and worst ways to create quadrature signals for any application

Webinar: Amplifiers for Synthesizer and Local Oscillator Generation: The Unsung Application
May 14, 2020 | 8am PST

Many amplifiers in a typical RF/microwave system are used for single frequency applications: for local oscillator and clock generation. However, amplifiers are typically designed and characterized only for signal applications. In this short (25 minute) webinar, we will discuss:
• Do gain flatness, IP3, and noise figure really matter for LO drivers?
• Phase noise: the impact of amplifier selection
• Save time with more usable amps: positive gain slope, positive only bias, and SWAP optimized drivers

Webinar: A Brief Guide to Mixer Spurs
April 30, 2020 | 8am PST

Spurious products can quickly overcrowd your output spectrum and destroy the dynamic range of your system if you aren’t careful. The threat of these spurs can be minimized if a designer can predict their exact frequency and power early in the design phase. In this short (25 minute) webinar, we will discuss:
• Where single tone intermodulation products come from within a mixer
• How to model a mixer to get close approximations of spurious levels
• How to get the most accurate prediction possible without sitting in front of a VNA

Webinar: Microwave Amplifier Biasing Made Easy
April 16, 2020 | 10am PST

Optimal amplifier biasing can make a direct impact on the performance of your system. However, choosing the correct bias levels for your application can be challenging, and there are a number of factors that are often overlooked. In this short (25 minutes) webinar, we will provide insight into:
• Important distinctions between amplifier topologies
• Biasing considerations to improve noise filtering, reliability, and electrical performance
• Heat: why it’s a stronger factor than you might think

Webinar: Baluns, Balance & Differential Signals
April 2, 2020 | 10am PST

Differential signals and circuits have a magical property: the ability to cancel undesired signals without filtering. In this short (25 minute) webinar we will present:
• The Three Mistakes Everyone Makes When Using Differential Circuits
• How Balanced Circuits Can Give You Better Noise Suppression, Spur Cancellation, and More Power
• The Best Balun to use for Every Situation
