LDMOS AMPLIFIER MODULE SCH0192AR0
DESCRIPTION
The RF module is an integrated TV linear amplifier designed for UHF band, this module employs push-pull
LDMOS technology in order to achieve very good efficiency, high linearity and reliability.
LDMOS transistors operate in AB class. It is a wideband amplifier over the full frequency, no adjustment is
required for the channel change. The board includes RF section amplifier, bias circuit, protection circuit and
matching networks. A silver plated copper plate is brazed with PCB in order to obtain low thermal resistance.
Providing a minimum of 200W Pk sync linear power, this module is the perfect amplifier for any broadband
UHF power transmitter.
