H a c k R F O n e

10 MHz to 6 GHz 20 MHz bandwidth (20 Msps quadrature) Half-duplex SDR transceiver

SLIDE 5

SLIDE 6

SLIDE 7

Direct ADC

Two channels
Differential, 1 V peak-to-peak
No anti-aliasing filter

SLIDE 8

SLIDE 9

Direct DAC

Two channels
Differential, 800 mV peak-to-peak
No anti-aliasing filter

SLIDE 10

Baseband Epansion Board

Will make direct ADC/DAC easier to use
Oscilloscope/DAQ
Function generator
Interface with external RF front-end

SLIDE 11

Full-Duplex

RF section is Half-Duplex
USB through ADC/DAC is Full-Duplex (at

reduced sample rate)

SLIDE 12

Operating Frequency

Design goal: 100 MHz to 6 GHz
After components selected: 30 MHz to 6 GHz
After beta: 10 MHz to GHz
Future: 1 MHz to 6 GHz ?
