250W Power Amplifier Tray Description
The 250-Watt Power Amplifier Tray accepts an RF On Channel signal from the 30-Watt
driver tray and amplifies the signal to a power level of 250 Watts.
2-Way Splitter Board (1308933)
The 2-Way Splitter Board splits the incoming RF signal from the 30W Driver Tray and
applies the two RF signal paths to (2) 600W PEP UHF Amplifier Pallets.
600W PEP RF Pallet (LDU601-C) x2
The 600W PEP RF Pallet amplifies an incoming UHF RF signal and provides +18 dB gain.
The pallet is powered by a +30VDC source. Two pallets are required.
2-Way Combiner Board (1308930)
The 2-Way Combiner Board combines the two RF output signals from each 600W PEP RF
Pallet.
Amplifier Control Board (1308936)
The Amplifier Control Board receives commands from the 30W Driver Tray to control the
250W Amplifier Tray. The board also monitors the status, faults and power levels of the
amplifier tray and sends these signals back to the 30W Driver tray to be monitored on
the Driver’s LCD display.
+12VDC Switching Power Supply (1308896)
The +12VDC Switching Power Supply Board supplies +12VDC to power the Amplifier
Control Board.
+30VDC Switching Power Supply (1308906)
The +30VDC Switching Power Supply supplies +30VDC to power both 600W PEP RF
Pallets.
