XAGYL XC420M 420-450MHz 1000mW miniPCI

The XC420M is a 1000mW TX power miniPCI radio module. It is designed for the 420MHz 70cm HAM frequency band to support high value applications. The XC420M assures low EVM (Error Vector Magnitude) at higher modulation rates to maintain low packet errors and maximizes data throughput. The design uses highly linear output power amplifiers in balanced mode to deliver linear power even at 64 QAM radio modulations while maintaining an EVM below 4%. With better RX sensitivity and high SNR (specs stated in field conditions), the XC420M is specially designed to deliver best performance in long range outdoor applications. The industrial grade design and enhanced resilience to RF surges and ESD makes it ideal for deploying in harsh environments.

The noise level of XC420M is extremely low due to advanced filtering, careful component selection and improved RF receive chain design. It is designed to work in noisy environments, amid powerful GSM base stations, where other modules would be rendered non functional.

Technical Information

The XC420M has a 10dB TX power offset from the internal system registers. For example, in order to achieve a 29dBm transmit output power, the system should be set to 19dBm. It is also recommended not to override the calibrated power settings as this will increase the packet error rate due to increased EVM.

The XC420M will be recognized by the operating system as a standard 802.11b/g card operating in the 2.4GHz band. This is by design and should be expected. Please refer to the following frequency conversion chart to determine the actual output carrier frequency.
