pa mphamvu amplifier
PA Power Amplifier kwa DVB-T COFDM TX Transmitter transmitter 1w 2w 5w 10w 15w
Module ya pa Power amplifier imazindikira kutulutsa kwamphamvu kwa siginecha ya RF. Pamene mphamvu yolowera ndi 12V, kulumikiza ku COFDM modulation board, mphamvu yotulutsa imatha kufika ku 1W (+30timatengera antenna zochotseka ndi ndodo kusankha kuti igwirizane ndi malo osiyanasiyana ogwiritsira ntchito)
Mawonekedwe
