The Perseus22 is Here


A Brand-New SDR

An Eagerly-Awaited SDR


The Perseus22 is a 4-channel, direct sampling receiver with continuous frequency coverage from 10kHz to 225MHz and a typical image rejection larger than 70 dB. All channels are sampled synchronously, by a high-SNR, 14-bits A/D converter, and a software-defined digital down converter processes them.


This is implemented on an FPGA, the outputs of which are routed to the host PC by a USB 3.0 controller, allowing wide-bandwidth IF applications.


The frequency coverage is split into 2 groups of channels (two for the VLF-HF frequency range, the others for VHF), each one capable of diversity reception. This can, it is claimed, reduce noise in the order of tens of dB.


All channels include an analogue RF front end, equipped with attenuators, preselection filters, and amplifiers.

The receiver enclosure is machined from solid aluminium and finished with a fine, non-reflecting, black surface treatment. Watch our website for more details.
