Amalfi Semiconductor

Amalfi Semiconductor was a fabless developer of high-performance CMOS radio frequency (RF) and mixed-signal semiconductors for cellular handsets. Its proprietary CMOS-based AdaptiveRF architecture delivered power amplifiers that extended battery life and talk time while reducing the size and cost of front-end cellular handset designs, shipping over 100 million CMOS power amplifiers. Battery Ventures led the company's $24M Series C in 2009, with further investment in 2012 alongside DCM and Globespan Capital Partners. Amalfi Semiconductor was acquired by RF Micro Devices (now part of Qorvo) in November 2012 for $47.5M in cash. The company is defunct as an independent entity and publishes no developer portal, documentation, or public API; this profile is retained for network and portfolio-graph completeness rather than API enrichment.

Amalfi Semiconductor is profiled on the APIs.io network. Tagged areas include Company, Semiconductors, RF, CMOS, and Power Amplifiers.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
