The Model 30S1G3 is a solid state, self-contained, air-cooled, broadband amplifier designed for
applications where instantaneous bandwidth, high gain and linearity are required. Housed in a stylish
contemporary cabinet, the unit is designed for benchtop use, but can be removed from the cabinet for
immediate equipment rack mo unting.
The 30S1G3, when used with a sweep generator, will provide a minimum of 30 watts of RF power.
Included is a front panel gain control which permits the operator to conveniently set the desired
output level. The 30S1G3 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 by 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
power supply fault has occurred. The unit can be returned to operate when the condition has been
cleared. The 30S1G3 digital panel provides control of all amplifier functions both locally and
remotely via IEEE-488 (GPIB) or RS-232 interfaces.
The low level of spurious signals and linearity of the Model 30S1G3 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.
