TGA2611-SM
2 – 6 GHz GaN LNA
Product Description
Qorvo's TGA2611-SM is a packaged broadband Low
Noise Amplifier fabricated on Qorvo’s QGaN25 0.25 um
GaN on SiC process. The TGA2611-SM operates from 2
to 6 GHz and typically provides >18 dBm P1dB, > 22 dB
of small signal gain and 30 dBm of OTOI with 1.0 dB NF.
In addition to the high overall electrical performance, this
GaN amplifier also provides a high level of input power
robustness which allows more flexibility in designing the
receive chain circuit protection.
The TGA2611-SM is available in a low cost, surface mount
20-lead 4x4 mm plastic QFN. It is ideally suited to support
both radar and satellite communication applications.
Both RF ports have intergraded DC blocking caps and are
fully matched to 50 ohms.

Electrical performance is measured under conditions noted in the
electrical specifications table. Specifications are not guaranteed over
all recommended operating conditions.
Exceeding any one or a combination of the Absolute Maximum Rating
conditions may cause permanent damage to the device. Extended
application of Absolute Maximum Rating conditions to the device may
reduce device reliability.
