Solid State Broadband High Power Amplifier
2135 – BBS3G6QHM
300 – 3800 MHz / 50 Watts
The BBS3G6QHM (SKU 2135) is suitable for ultra broadband high
power linear applications, laboratory, and RFI/EMC susceptibility
testing. This dual band amplifier utilizes an LDMOS Amp for 201000MHz band and a GaAsFET Amp for high band frequency
response. Employing advanced broadband RF matching networks and
combining techniques, EMI/RFI filters, and all qualified components
achieve exceptional performance, and high efficiency. The system
includes a universal voltage, single phase, power supply and a built in
forced air-cooling system. Empower RF’s ISO9001 Quality Assurance
Program assures consistent performance and the highest reliability.
