Experienced RF Engineer provides information that makes RF design understandable

Over many years working as RF engineers we have come across engineers who consider RF design to be akin to black magic. This may be because engineers do not have the right design and analysis models to approach RF design and get lost in the details of many technical areas Electromagnetics, Circuit Design, RF PCB Layout, Mathematics and Embedded Firmware Programming. To make effective RF design decisions we must have the right design and analysis models and be able to see the big picture.

Below are links to articles which distill our years of experience as RF engineers. These are written in the rare moments of leisure and have a casual tone but hopefully they will make RF design more understandable. We have found that once a person has the big picture it is easier to go into details. If there is an area that you would like us to write an article about please let us know using the form at the end of the page.

If you require more direct assistance from a RF engineer in your projects we will of course be happy to provide our services :-). We can do all of your project or assist you with a part of it or simply be on call for any issues you may have. Besides RF device design we can advise you on complete solutions from network architecture, site surveys to antenna selection and placement.

We do numerous RF designs a year and when you retain us you are able to leverage our library of RF designs so that your RF design gets done fast and at low cost.

We design for all commonly used RF bands - HF, VHF, UHF, 900 MHZ ISM and 2.4 GHz ISM and microwave.

We can integrate the system controller, data logging and wire line communication functions RF device into one module. This results in a highly integrated device. The overall cost, power consumption, and size are all lower while performance are higher. We have designs that integrate the data radio with Ethernet, RS-232, RS-485, relay closures and data logging functions.

Our devices have transmit powers from milli Watts to Kilo Watts. To minimize power consumption and to reduce interference the output power on our RF designs is software controllable. We can design RF devices that transmit from short distances to hundreds of miles.

Our custom designs utilize the latest modulations schemes and protocols to offer highest possible data rates at costs that are a fraction of the costs of off the shelf devices.

With a custom design you only use the components that you need and usually have a much tighter integration between the controller and the radio segments. All this results in the device being the smallest size possible.

We ensure that your entire device passes FCC certification and is ready to be deployed.

Our software allows YOU to customize the device to your needs. All our designs have a boot loader feature allowing you to change to code. They are field upgradable thus lowering operating costs. We provide the development system and system libraries enabling you to develop your own customized software.

Modern micro controllers and RF chips are highly integrated and deliver previously unheard of performance. Our use of latest technology allows our low power devices to achieve performance previously available only in bulky high end systems.

The packaging can be customized to fit your application. Whether you need a metal enclosure with external heat sinks for heat dissipation, small rugged unit or a potted unit for marine applications we can provide it.

We will provide you with a production ready design or can manufacture the units for you. If a large production volume is needed our partners in Asia can make it for you cost effectively. For smaller runs the devices can be cost effectively made here in the US.
