RadioProcessor
Transmitter Output Level
There are currently two different options for RadioProcessor transmitter output voltage. The standard gain
RadioProcessor has an output voltage of one volt peak-to-peak at 10 MHz, with a 3 dB bandwidth of about 85
MHz. The high gain transmitter output amplifier has a maximum output voltage of about 3.75 Volts peak-to-
peak, with a 3dB bandwidth of about 21 MHz, while covering the same frequency range as the standard gain
board. Figure 4, below, shows the transmitter output voltage vs. frequency plot for the two RadioProcessor
options. Please contact SpinCore for more information.

Figure 4:
RadioProcessor transmitter output voltage vs. output frequency.
The dotted line represents the standard gain transmitter output amplifier, and the
solid line represents the high gain transmitter output amplifier. The voltage
values are for 50 Ohm load impedance. The 0 dB (1 mW, 0.63 Vpp on 50 Ohm)
output value for both transmitter amplifiers occurs at approximately 90 MHz.
