Plextek RFI is has a growing library of video tutorials on various aspects of Microwave/MMIC design.They feature examples of past design IP that we can use to help develop custom products for our clients with reduced risk and timescales.
Videos can be viewed by clicking the individual links below, or by visiting the Plextek RFI YouTube channel.
Helen Duncan interviews Rob Smith on useful tips for GaN Power Amplifier Design
In this video Stuart Glynn describes the design of an X-band GaN PA using a GaN process from UMS, on keysight’s ADS simulator
Liam and Helen Duncan present the second of our “Technical Discussions” series on the advantages of custom MMIC design.
Liam and Helen Duncan present the first of our “Technical Discussions” series on the future use of mm-waves in 5G
Liam presents the design of a 4-channel Power Amplifier IC with in-built phase control, for 5G front-end applications
In this video Andy explains intermod products in amplifiers. In particular, 2-tone OIP2 is explained, and compared to 1-tone second harmonic intercept point.
In this tutorial Andy describes the design of an octave-bandwidth double-balanced MMIC frequency doubler using a quad-diode bridge, and two types of planar Marchand baluns
This video is a follow on from Stuart’s video on the 15GHz Point to point GaN MMIC PA. In this talk Tony puts a complex modulation scheme through the GaN PA and simulates distortion, eye-diagrams & EVM etc. using MATLAB.
In this video Stuart explains the design of a compact GaN PA MMIC
for use in Linear Point to Point applications at 15GHz.
This is a recording of a recent paper presented by Liam at the
UK ARMMS conference.
Planar spiral baluns are often used in MMIC mixers, for example.
In this video tutorial Andy describes their design and layout, and shows their use in a double-balanced diode mixer.
GaN technology is well suited to the realisation of Power Amplifiers.
In this video tutorial Stuart describes the design, layout and simulation
of a 2-18GHz GaN PA MMIC using Keysight ADS.
Liam Devlin describes a design methology for broadband
PHEMT MMIC switches using Keysight’s ADS simulator
Graham Pearson shows how to perform a RF-On-Wafer
calibration using an Impedance Standards Substrate from
Cascade Microtech, & then moves on to measure a GaAs MMIC amplifier.
Andy Dearn demonstrates a mm-wave double-balanced
switching FET mixer using harmonic balance simulation.
Andy shows how to design high frequency oscillators using small
and large-signal techniques.
Stuart Glynn describes rms phase error in
microwave phase shifters.
Andy discusses integrated (MMIC) filters on
Keysight’s ADS simulator.
