The Amplifier Research 25S1G4 is a solid-state, broadband amplifier offering 25W minimum output across 0.8–4.2 GHz with 44 dB gain and ±1.5 dB flatness. Designed with air-cooled, forced ventilation, it ensures stability under mismatched conditions, faithfully reproducing AM, FM, and pulse modulation. The front panel digital display provides operational status and fault monitoring, while protection circuits safeguard against overdrive and overheating.
With remote control via IEEE-488 (GPIB) and RS-232, the 25S1G4 suits wireless communication testing, including CDMA, W-CDMA, TDMA, GSM, and EMC applications. Its low spurious levels and linear performance make it an excellent driver amplifier.
