Brief Description

The ATB010 is a small, low cost, PCB-based RF technology demonstrator aimed at speeding

manufacturers' design and development of dPMR/PMR446 transceiver products. The board is designed

as a plug-in to the CML *DE6181 demonstration kit. Along with a *PE0002 host controller a full RF

transceiver can be assembled to offer a variety of voice and data options configurable via Function

Image™ and control scripts.

All the necessary RF circuits are provided on the ATB010 PCB: receiver and transmitter VCOs, a

500mW RF power amplifier, harmonic filter, antenna switching, LNA, RF to IF mixer and limiter

discriminator IF processing. The RF performance is designed to be compliant with EN 301 166 (6.25kHz

dPMR) and EN 300 296 (12.5kHz PMR446). The DE6181 demonstration kit is a flexible platform that

can provide both digital (dPMR) and analogue (PMR446) functionality.

The design is production-engineered for low bill of materials cost, with a minimum number of component

types and values and uses only low-cost off-the-shelf components. The design uses a single 3.6V

supply, e.g. 3 AAA cells or a Li-ion battery.

*DE6181: Demonstration Kit for CML’s CMX618 and CMX7141.

*PE0002: Evaluation Kit - a global interface system for use with evaluation kits for CML's new generation

ICs, including FirmASIC
