RF Design and Wireless Controls

We have special expertise developing RF transmitter and receiver systems. In addition to developing systems for the OEM market, we also sell products under the Martec Access Products brand name. We primarily design for the 250 - 450 MHz frequency range, and are expert in maximizing performance within FCC limitations, working with a variety of coding sequences, including rolling code and encrypted formats, and keeping costs low.

We have a variety of design techniques that we employ depending on the cost and performance targets of the product, including LC and SAW transmitters, and super-regen and chipset-based receivers.

Our ability to design the circuit, lay out the board for best radiation performance, write the microcontroller software, and design the housing and buttons all under one roof gives our customers a powerful tool for bringing products to market as quickly as possible.
