 Product information
♦ NEW FEATURES of V4: added safety and security
♦ Auto power on from 50mW input it will power up if no RF signal input it will idle at zero
current, so it can now be left powered on all day long
♦ LED indicator one dual color, red-green
♦ Green lit constantly = all is perfect, RF level in is fine, and DC supply is fine
♦ Green off blinks start at 150mW and down to 50mW, longer and longer off time = less input
power
♦ Red blinks show input voltage is under 6.8V
♦ longer and longer RED lit time when voltage drops more.
♦ Green and Red blinks can be active at the same time in case both low rf level and low voltage
booster still works at different voltages, and can now be powered as low as 2-3V
♦ The booster will give good power from 125mW to 500mW input
500mW is nominal input, 125mW is -6dB accepted max cable loss, at this point output will
drop 1db input will survive 1W for 10 sec, and 2W for 2 sec, maybe more but I did not dare
to test the kill time
♦ The previous booster versions had idle currents in the 400-600mA range, so booster could
not be left powered on when not flying risk of using all battery power existed. Users with
V3.x boosters must be aware of this.
♦ Idle current is defined as the current the booster draw with no RF input
♦ Idle current for booster V4 is only 1.4 mA !
♦ This tiny PA booster is designed to get 500mW input from the V3 RC system
♦ Boosting 0.5W to 7W will increase the range by at least a factor 3 !
♦ The PA module consume about 2A at 7.2V and give 7 to 8 Watt out of pure long distance RF
