Echotek Series RFM 251 XMC Tuner 20 MHz to 2.5 GHz

Product Description

Flexible RF Tuning With Digital IF Output on an XMC 
The Echotek Series RFM-251-XMC tuner from Mercury Computer Systems is engineered for applications that require RF tuning and data conversion flexibility within a compact slot-saving package. Tuning over a broad frequency range and then converting to digital IF, this XMC delivers the functionality required for applications that must operate under SWaP-constrained platforms.

Broad Frequency Range and Onboard FPGA Processing 
The RFM-251-XMC tuner supports a broad frequency range from 20 MHz to 2500 MHz. This coverage is ideal for intercepting frequencies associated with a wide range of communication bands. The instantaneous dynamic range is 75 dB typically with 10, 40 or 160 MHz standard IF bandwidths. The IF is pre-digitized via a high fidelity analog-to-digital converter and routed into a Virtex-6® FPGA where filtering and protocol processing occurs. Currently supported protocols include Serial RapidIO® and PCIe with data streaming in the VITA 49 digital IF data format.

Channel Density With 6U/3U XMC Carriers and SBCs 
The RFM-251-XMC mezzanine can be hosted on VME, VXS, OpenVPX 6U or any baseboard that can host VITA 42 compliant XMCs. Typically powered by Intel® or PowerPC® processors, 6U carriers are capable of hosting up to two XMC tuners while retaining single slot width. Smaller 3U carriers support single XMC sites. Total power draw for this Echotek Series Tuner is 15 watts. Unprecedented channel/processing density is achievable when RFM-251-XMC tuners are coupled with carrier boards. Multi-channel coherency and synchronization is achievable via 1 PPS and 10 MHz references.
