Based on the Peregrine Semiconductor's PE4306 chip, this module is a complete RF 0-31 dB attenuator with 1 dB steps, for 50 ohm systems 

on a 20 x 31 mm PCB and has a universal SPI interface. 

It draws under 100 uA at 3VDC and no negative voltage is required for it's operation since the chip has an internal negative voltage generator.


You can download its schematic and building instructions from our website SV1AFN
