MODEL 25S1G4

M1, M2, M3, M4

25 WATTS CW

0.8 – 4.2 GHz

The Model 25S1G4 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 mounting.

The 25S1G4, when used with a sweep generator, will provide a minimum of 25 watts of RF power.

Included is a front panel gain control which permits the operator to conveniently set the desired

output level. The 25S1G4 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 25S1G4 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 25S1G4 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.
