The WiNRADiO WR-G527e is a versatile receiver platform of USB-interfaced modular building blocks suitable for high-performance signal intercept, acquisition and monitoring applications, precision direction finding and beam-forming.

The WiNRADiO WR-G527e is designed to be a compact, low-cost front-end of choice for Software-Defined Radio applications wherever an instantaneous IF bandwidth greater than 20 MHz is required. The robust, low-power tuner can be deployed in fixed, land mobile, or airborne installations, and is able to support single-channel as well as multi-channel phase-coherent applications with excellent phase and amplitude matching between channels.

For frequencies above 20 MHz, the receiver is based on a double-conversion process, where the incoming frequency is down-converted to the output frequency 70 MHz, which is provided as a filtered output ready to be digitized. The IF paths are switchable in order to minimize images and spurious mixing products. Filters are specially selected to ensure flat phase response and digitally controlled attenuators are employed in the front-end as well as in the IF path.

For frequencies 0.01 to 30 MHz, an amplified bypass output is available for a direct connection to a DSP back-end. The entire system features an excellent phase stability and flatness throughout the entire frequency range, with minimum amplitude and phase distortion, as well as minimum amplitude and phase mismatch between channels.
