At IMS 2025, RFMW’s Steven Darrow speaks with Jim Ahne from Guerrilla RF to discuss the release of the GRF6411 and GRF6412—innovative digital variable gain amplifiers (VGAs) that integrate a high-performance gain block with a digital step attenuator (DSA).
Engineered for demanding RF environments, these next-gen devices introduce Rapid Fire™, a unique hybrid control feature enabling instantaneous toggling between two pre-programmed attenuation states. This breakthrough is especially valuable in applications like blocker suppression and A/D protection in telecom, mil-aero, and SATCOM systems.
Key topics covered:
- GRF641x product architecture
- Benefits of integrated gain block + DSA design
- How Rapid Fire™ enables fast attenuation switching
- Use cases: In-band blocker mitigation, receiver protection
- Sample availability, evaluation kits, and production timeline
Now sampling to select customers, full production Q4 2025.
