Fidus RF designers draw from their extensive experience in diverse industries: telecommunications, aerospace and defense, consumer products, transportation, wireless devices and others, to deliver full, turn-key system designs. Fidus can assign an integrated team to your project, including system architects, hardware and PCB layout experts, FPGA, DSP and Signal Integrity/EMC specialists. 

From concept to proven prototype, our designers deliver comprehensive RF systems. Designing in frequencies up to 26 GHz, our designers have expertise in diverse technologies, such as WIFI/WLAN (802.11), GSM, WiMAX (802.16), WCDMA and CDMA, OFDM, Millimeter Wave, Software Defined Radio (SDR) and RFID.

Fidus also designs solutions to integrate RF systems with FPGAs, DSPs and switching power supplies in your product. We deliver your project on time and on budget.

Fidus RF project examples include:

Global Positioning System (GPS) Technology
Fidus hardware, firmware and PCB layout designers developed this battery-powered, portable unit to receive GPS and sensor  information, convert the data into a proprietary message structure and transmit the packet to a satellite network. Designed to be water resistant, the unit supported several different battery types, external sensors, and both internal and external antennae.

Radio Frequency Identification (RFID) Tag
We’ve solved RF circuit issues in a device consisting of RFID Tags, Tag Reader and system software. As well, we’ve performed extensive antenna modelling for RFID applications. Our RF expertise and experience designing Software-Defined Radio products enables us to bring innovative techniques to RF design.

Point-to-point, K band (24 GHz) microwave link
This product provides secure, extended range connectivity by transparently sending traffic over a point-to-point K band microwave link. Designed for outdoor, weatherproof applications, the device combines several diverse technologies into a single integrated system.

Software-Defined Radio (SDR) / Automatic Identification System (AIS) Transceiver
This SDR device has both airborne and maritime AIS applications. A frequency-agile product, it is capable of transmitting and receiving on all authorized AIS channels. A standard NMEA 0183 data-path and proprietary control path provide the back-end interfaces. Software-defined-radio (SDR) technology, in which the VHF band is directly sampled by a high-speed analog-to-digital converter, keeps the physical size to a minimum, as well as improving the device’s flexibility and agility over various frequencies. Digital processing enables the product to exceed the M.1371 analog specifications, including a very wide dynamic range.
