Description
Overview
The Amplifier Research 350S1G6 is a solid-state, Class A microwave amplifier designed for broadband RF applications requiring high instantaneous bandwidth, gain linearity, and output power. This self-contained, air-cooled unit delivers a minimum of 350 watts of RF power across the 0.7–6.0 GHz frequency range, with exceptional spurious suppression and phase linearity. The front panel gain control allows precise output level adjustment, while an integrated RF input leveling circuit protects against overdrive conditions.
Key Features
- 350 watts minimum rated power output across 0.7–6.0 GHz instantaneous bandwidth
- 58 dB minimum gain with continuous adjustment range of 10 dB minimum, 4096 remote steps
- Class A solid-state design with low spurious distortion (–73 dBc typical)
- Gain flatness of ±1.5 dB typical and ±2.5 dB maximum
- Harmonic distortion: –20 dBc maximum at 250 watts
- Third-order intercept: 63 dBm typical; noise figure: 10 dB typical
- Faithfully reproduces AM, FM, and pulse modulation on input signal
- 100% mismatch tolerance with rated power—operates safely with any impedance magnitude and phase
- Remote control via GPIB/IEEE-488, RS-232 hardwire, fiber optic RS-232, USB 2.0, and Ethernet
- Digital front panel display shows operation status and fault conditions
- Automatic over-temperature protection with DC voltage removal if cooling fails
Applications
- Driver amplifier for wireless and communication component testing (CDMA, W-CDMA, TDMA, GSM)
- Multi-band test instrument for RF subsystem validation
- EMC testing requiring undistorted modulation envelopes
- High-linearity RF power amplification for communication system testing
