Product Overview

AMPLIFIER RESEARCH 120S1G3

The Amplifier Research 120S1G3 Microwave Amplifer is a portable, self-contained, air-cooled, broadband, completely solid-state amplifier designed for applications where instantaneous bandwidth, high gain and linearity are required. Push-pull circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability. The AR 120S1G3, when used with a sweep generator, will provide a minimum of 120 watts of RF power.

The AR 120S1G3 is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier. The DCP uses a digital display, menu assigned softkeys, a single rotary knob, and four dedicated switches (POWER, STANDBY, OPERATE and FAULT/RESET) to offer extensive control and status reporting capability. The display provides operational presentation of Forward Power and Reflected Power plus control status and reports of internal amplifier status. Special features include a gain control, internal/external automatic level control (ALC) with front panel control of the ALC threshold, pulse input capability and RF output level protection. Also included is an internal RF detector which provides an output for use in self-testing or operational modes.

All amplifier control functions and status indications are available remotely in GPIB / IEEE-488 and RS232 format. The buss interface connector is located on the back panel and positive control of local or remote operation is assured by a keylock on the front panel of the amplifier. The low level of spurious signals and linearity of the Model 120S1G3 make it ideal for use as a driver amplifier in testing wireless and communication components and subsystems. It can be used as a test instrument covering multiple frequency bands and is suitable for a variety of communication technologies such as CDMA, W-CDMA, TDMA, GSM etc. It is also suitable for EMC Test applications where undistorted modulation envelopes are desired.

Specifications of the Amplifier Research 120S1G3 include:

RATED POWER OUTPUT ...............................................120 watts minimum

INPUT FOR RATED OUTPUT..........................................1.0 milliwatt maximum

POWER OUTPUT @ 3dB COMPRESSSION

Nominal................................................................140 watts

Minimum...............................................................120 watts

POWER OUTPUT @ 1dB COMPRESSION

Nominal................................................................122 watts

Minimum...............................................................100 watts

FLATNESS.....................................................................±1.5 dB typical

±2.0 dB maximum

±1.0 dB Internal Leveling

FREQUENCY RESPONSE ...............................................0.8 – 3.0 GHz, instantaneously

GAIN (at maximum setting) ...........................................51 dB minimum

GAIN ADJUSTMENT......................................................(Continuous Range)

15 dB minimum

(4096 steps remote)

INPUT IMPEDANCE.......................................................50 ohms, VSWR 2.0:1 maximum

RF POWER DISPLAY ......................................................0–150 Watts

OUTPUT IMPEDANCE ...................................................50 ohms, nominal, VSWR 2.5:1 maximum

MISMATCH TOLERANCE...............................................100% of rated power without foldback. Will operate without damage or

oscillation with any magnitude and phase of source and load impedance. (See

Application Note #27)

MODULATION CAPABILITY...........................................Will faithfully reproduce AM, FM, or pulse Modulation appearing on the input

signal.

THIRD ORDER INTERCEPT .............................................See chart. The third order intercept points for this chart have been determined

using two tones spaced 1 MHz apart. This is typical for W-CDMA systems. Closer

tone spacing such as 60 kHz generally provides about a 1db to 3db

improvement in the IP.

HARMONIC DISTORTION.............................................Minus 20 dbc, max at 100 watts

SPURIOUS ....................................................................Minus 73 dbc Typ.

PHASE LINEARITY..........................................................± 1.0 deg/100 MHz, Typ

PRIMARY POWER ..........................................................(Selected Automatically)

90-132, 180-264 VAC

50/60 Hz, single phase

1200 watts maximum
