1. GENERAL INFORMATION
1.1 GENERAL DESCRIPTION
The Model 150/150AW1000 is a self-contained, broadband solid-state amplifier designed for laboratory
applications where instantaneous bandwidth, high gain, and moderate power output are required. A GAIN
control, which is conveniently located on the unit’s front panel, can be used to decrease the amplifier’s gain by
20 decibels (dB) or more. Solid state technology is used exclusively to offer significant advantages in reliability
and cost. A Model 150/150AW1000, used with a frequency-swept signal source, will provide 150 watts of
swept power output from .01–1000 megahertz (MHz). Typical applications include antenna and component
testing, wattmeter calibration, and electromagnetic interference (EMI) susceptibility testing, as well as usage as
a driver for frequency multipliers and high-power amplifiers. The Model 150/150AW1000 can be operated
locally by using the unit’s front panel controls, or remotely by using the unit’s IEEE-488, RS-232 interface,
USB, or Ethernet interface.
Special features incorporated into the Model 150/150AW1000 include the following:
• A Control Panel that allows both local and remote (via a computer interface) control of the amplifier
(including adjustment of the amplifier’s RF Gain during CW mode operation) and provides graphical
displays of the amplifier’s Forward and Reflected power levels.
• A General Purpose Interface Bus (GPIB)/IEEE-488.2 interface for remote control of the amplifier’s
operating functions.
•
RS232 serial communications including both wire and fiber-optic ports for remote control.
•
USB Communication port for remote control.
•
Ethernet Communication port for remote control.
•
Protection is provided by DC current limiting, over-temperature shut down and RF power limiting.

1.3 POWER SUPPLIES
The Model 150/150AW1000 contains three switching power supplies. The input voltage range to the power
supply is 100–240 VAC, 50-60Hz, selected automatically. The AC input power is approximately 500 watts.
PS1 is a multiple output supply. PS1 has a +5volt, standby supply for the A12 Control/Fault board and the A14
Interface board used for the remote interfaces. The -15V is supplied to all of the RF modules in the amplifier
configuration. The
+
15V is supplied to the A2 module. The +24V DC is supplied to module A1 and cooling
fans B1 thru B3.
PS2 su32V to the A2 Module and the A9 Regulator Assembly.
PS3 is a single output supply. The +24 VDC output supplies voltage for modules A3, A6 and A7.
