1. Introduction
1.1. Purpose
This Document will provide the design constraints for the inclusion of the 7700H TRX into a Cattron-
Theimeg Inc. product capable of meeting the requirements of FCC part 90, DOD chapter 5.3.2, ETSI 300-
220v2.1.1, this module will be configured by software and cover the frequency ranges of 450MHz to
470MHz. and power ranges 1mW to 500mW.
Modulation schemes supported will be, 2GFSK and 2RCFSK.
This design is to be based on the latest generation Analog Devices ADF7021 High Performance Narrowband
ISM Transceiver IC.

1.3. Definitions, Acronyms, Abbreviations
1.3.1. Definitions
• Anomaly. Anything observed in the documentation or operation of software that deviates from
expectations based on previously verified software products or reference documents. A critical
anomaly is one that must be resolved before the V&V effort proceeds to the next life- cycle phase.
• Third Party Testing. The verification testing required to be carried out by an authorized body.
