Amplifier Research 30S1G3
The Amplifier Research 30S1G3 is a state-of-the-art solid-state, self-contained, air-cooled, broadband amplifier meticulously engineered for applications demanding instantaneous bandwidth, exceptional gain, and superior linearity. Designed primarily for benchtop use, this versatile amplifier can also be easily rack-mounted to fit seamlessly into your laboratory or testing environment.
When paired with a sweep signal generator, the 30S1G3 delivers a formidable output of a minimum of 30 watts of RF power. Its user-friendly front panel features an intuitive gain control, allowing operators to effortlessly adjust the desired output level. Advanced protection mechanisms safeguard the 30S1G3 from RF input overdrive through an innovative RF input leveling circuit, which maintains optimal RF levels during fluctuations above 0 dBm. Additionally, the RF amplifier stages are fortified against over-temperature conditions, automatically cutting the DC voltage supplied to them if ventilation is compromised or if a fan failure occurs.
The digital display positioned on the front panel clearly conveys the operational status and promptly alerts users to any fault conditions, such as over-temperature or power supply issues. Once the concern is addressed, the 30S1G3 can be quickly reset to normal operation. Comprehensive control of all amplifier functions can be achieved both locally and remotely via IEEE-488 (GPIB) or RS-232 interfaces, integrating smoothly into a variety of test setups.
With low levels of spurious signals and outstanding linearity, the Model 30S1G3 stands out as an ideal driver amplifier for testing wireless and communication components. It is compatible with a wide range of communication technologies, including CDMA, W-CDMA, TDMA, and GSM, making it an essential tool across numerous applications, including EMC testing, where undistorted modulation envelopes are critical.
