LDMOS UHF AMPLIFIER MODULE
DESCRIPTION
The MTF0070C is the RF Amplifier module of the AUTV/1500LD based on LDMOS technology. The RF
Amplifier module is composed by eight broadband amplifier boards (SCH0192A) coupled together by
means of Wilkinson combiners, driven by means another amplifier board. The module also includes the
cooling heatsink and a small Interface board (SCH0221A) which forwards power supply to the two stages,
groups the power and temperature into a single connector, more easily managed inside the transmitter. The
driver stage of the amplifier module is provided with a Gate control to inhibit the output power.
