The Model 60S1G3 is a solid state, self-contained, air-cooled, broadband amplifier designed fo
applications where instantaneous bandwidth, high gain and linearity are required. Housed in a stylis
contemporary cabinet, the unit is designed for benchtop use, but can be removed from the cabinet fo
immediate equipment rack mounting.
The 60S1G3, when used with a sweep generator, will provide a minimum of 60 watts of RF power.
Included is a front panel gain control which permits the operator to conveniently set the desired outpu
level. The 60S1G3 is protected from RF input overdrive by an RF input leveling circuit which controls
the RF input level to the RF amplifier first stage when the RF input level is increased above 0 dBm.
The RF amplifier stages are protected from over-temperature
y removing the DC voltage to them if an
over-temperature condition occurs due to cooling blockage or fan failure. There is a digital display on
the front panel to indicate the operate status and fault conditions if an over-temperature or powe
supply fault has occurred. The unit can be returned to operate when the condition has been cleared.
The 60S1G3 digital panel provides control of all amplifier functions both locally and remotely vi
IEEE-488 (GPIB) or RS-232 interfaces.
The low level of spurious signals and linearity of the Model 60S1G3 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.

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.
