Anokiwave
has excellent design capabilities. Here
are a few examples of the products we have designed,
continue to develop and offer to our clients.
High
Power Switches
Examples below show a 6-18 GHz 10W H/V
switch and a >10W X-Band switch-limiter designed in
PIN HMIC technology. Extensive EM simulations were needed.
The 6-18 GHz has channelized microstrip completely modeled
in Sonnet's EM. Besides the PIN switches we have expertise
in pHEMT and MESFET switches as well.

Passive
Component Design
Additional examples of work previously
completed by Anokiwave includes EM design and optimization
(article)
of a number of distributed and lumped passive structures
on planar and non-planar substrates. Expert use of electromagnetic
simulation allows very accurate designs. Figures show
accuracy of some of the designs in microstrip medium.
Our extensive experience in modeling interaction between
neighboring circuits allows us to shrink circuit size
and accurately design passive circuits. A lot of the
passive circuit designs are implemented in lumped components
- inductors and capacitors instead of transmission lines.
Anokiwave has successfully lumped distributed circuits
even well into mm-wave region. Generally speaking going
from distributed circuit to a completely lumped circuit
can reduce circuit size by 50% or more. This more than
justifies design expenses incurred during the NRE.
In addition, Anokiwave has expertise
in simulating a variety of circuits such as connectors,
waveguide discontinuities, filters, packages and package
transitions, loss estimation of various circuits, filters
and other passive structures. We do this by using traditional
models in a circuit simulator and then improve the models
using EM simulators such as Sonnet and HFSS (as
described here).

Automotive
Radar
The automotive market is using mm-wave
frequency for range estimation. Both near and far range
sensors are being developed. The emerging requirements
of large volume mm-components has created new challenges
of designing with "course" lithographic tolerance used
in PCB technology. Integrating the chipset into an RF
module can be a problematic issue and requires careful
attention. In addition, the high mm-wave frequencies
have some unique issues such as measurements, moding
and coupling. Anokiwave can help you develop products
for the automotive market by:
- Statistical EM simulations
- Design centering using EM simulation
- Working closely with manufacturing
and as a team member to identify the key parameters
to optimize and design center
- Designing process tolerant
components
- Configuring the RF module architecture
- Designing difficult components
such as passive multipliers and transitions
Anokiwave has extensive experience with
working and designing automotive products. For example,
Nitin Jain, the firm's CTO, was technically responsible
and conceived the 77GH mm-module design presented in
the paper titled "A
76-77GHz PULSED-DOPPLER RADAR MODULE FORAUTONOMOUS CRUISE
CONTROL APPLICATIONS". On first assemble and test,
the design worked as predicted with no tuning or metal
etching and met all the design specifications.

LMDS
The recent deployment of mm-wave
fixed wireless LMDS systems has created the need for
commercial production of 26-40 GHz components used for
the RF module of the LMDS units. This has created new
challenges for designing with lithographic tolerances
that are inadequate for mm-wave production, high frequency
integration difficulties and other complications of
mm-wave's such as measurements, moding and coupling.
Anokiwave can bring your product from low yields to
respectible yields by:
- Statistical EM
simulations
- Design centering using EM simulation
- Working closely with manufacturing
and as a team member to identify the key design parameters
- Designing process tolerant components
- Designing the mm-wave RF module
- Modeling of the passive component
and the PCB
Anokiwave has extensive experience working
closely with the automated manufacturing teams that
manufacture LMDS equipment in large volumes and of increasing
the yields many-fold while improving the product quality.
