POWER SERIES II
180W 869-894MHZ RF POWER AMPLIFIER
USER MANUAL
1. GENERAL DESCRIPTION
The Power Series II 180W, 869-894MHz Power Amplifier is a high power amplifier (PA) that incorporates LDMOS
technology to provide high efficiency and rugged operation. It is developed for cellular application. The PA
features various alarms and protection circuitry, Automatic Level Control (ALC) and cooling fans.
2. INSTALLATION
Note: Make sure the PA’s output port is
appropriately terminated before applying any
RF input signal.
Connect the RF input signal to the PA’s input port labeled RF IN. Connect the PA’s output port labeled RF OUT to
a RF load or an antenna. Connect a DC power supply source to the terminal block labeled + -. Apply the required
26VDC @ 20A voltage. After going through an initialization state, the PA’s DC POWER LED (green) and RF
INPUT LED (red) should be on. Apply and then slowly increase the RF input signal (20W max, 869-894MHZ).
Monitor the RF output. Continue increasing the RF input level until 180W is reached at the RF output port. RF
INPUT LED should turn off. TX ON LED (green) should turn on. The PA is now transmitting. No other
adjustment is necessary.
