2. Development of Millimeter Wave 

MMIC Design Environment 

using 

Ansoft Designer/Nexxim 

Designer/ Nexxim ver.3

Millimeter Wave application 

Why do we need millimeter wave at now? 

Change of mobile communication 

Page-12 

analog sound -> convolution of control date -> digital sound -> digital data 

-> still picture -> movie..... 

Expansion of IP based network to achieve ubiquitous networking 

requires seamless connection between fixed network and mobile network 

[Problem] 

Short of communication band 

Advantages of millimeter wave 

[Countermeasures] 

Modulation method -> OFDM, MIMO.... 

Higher frequency -> Millimeter wave.... 

less interference with other systems / no other system in this band / easy to 

control directivity / physical concealment due to propagation characteristic / 

absorbed in the air / hard to diffract / 7 GHz bandwidth available without license …

Page-13 

Millimeter Wave application 

What is difficult in mmW MMIC design? 

Wave length < 10mm 

-> Elements, circuit, connection accuracy < 1-10um 

-> needs to realize as Microwave Monolithic IC 

-> MMIC Designers need knowledge of all circuit blocks. 

Transistor characteristics, VCO, Mix, LNA, PA, Filter, Antenna, system.... 

Lumped elements -> influence of parasitic elements 

Distributed elements -> narrow frequency range

Which is better, Planar EM or HFSS for mmW MMIC? 

Planar EM 

- Good affinity with schematic circuit 

direct and seamless EM analysis 

- Ideal EM signal port 

- Simulation with conductor thickness is slow. 

HFSS 

- High accuracy 

- Fast simulation with conductor thickness 

- Signal port has paracitic element . 

'Planer EM' is good for mmW MMIC design
