Page 5: Precautions
Make sure the following considerations have been made before applying power to the amplifier. 1) Be sure your load can appropriately dissipate the maximum power being applied by the amplifier. 2) When applying an RF signal, work with low duty cycles to limit the power being dissipated. http://www.spincore.com 2010-07-30... -

TTL signal source capable of sourcing at least 10 mA. A logical high signal is required to deblank (enable) the PA10W. The deblanking bit must be set at least 3 ms prior to sending the RF signal or optimal power will not be achieved. - Page 8 RF Input RF Output Figure 3: Representation of the deblanking and RF input and output signals to the PA10W. The PA10W requires at least 3.0 ms of deblanking time prior to the RF pulse for full output power. http://www.spincore.com 2010-07-30...
