Rincon Research Corporation’s (RRC) RFXR is becoming deprecated. It is a compact, low-power RF transceiver. When combined with the LPFE base card, numerous software-defined radio (SDR) and digital signal processing (DSP) applications are possible, many of which can operate standalone, without a host server or laptop. Typical applications include:

• Signal modulation and demodulation
• F1/F2 coherent RF repeater
• RF to disk
• Test signal/beacon transmitter, aligned to external 1 PPS and 10 MHz signals
• Sub-band tuning and channelizing
• RF-to-packets for RF signal transport over networks (digital IF)
• RFXR is based on the Analog Devices AD9361 transceiver IC. This IC contains direct-conversion architecture (zero IF or I/Q) dual-channel receivers and transmitters. RRC has carefully engineered the receiver front-end circuitry to achieve high performance without the need for external filters or LNAs.

The receive channels share a common receiver LO, can tune from 70 MHz to 6 GHz, and offer a runtime configurable IF bandwidth from 200 kHz to 56 MHz. Receiver gain can be independently adjusted from 1 dB to 60 dB in 1 dB steps.

The transmit channels share a common transmitter LO, can tune from 70 MHz to 6 GHz, and also offer runtime configurable IF bandwidth. Maximum transmitter power is about +4 dBm, with more than 90 dB adjustment range in ¼ dB steps.

RRC’s RFXR interface IP provides high-accuracy, high-precision time-tagging of receiver data. Even at low sample rates, our time-tags are accurate to within a few nanoseconds, providing true sub-sample precision for demanding applications!

RFXR is a core component of the MBRA2 RFXR SIGINT recorder and the LPFE RFXR MountainBrik™ systems.
