MGA-16116
Dual LNA for Balanced Application 450 – 1450 MHz
Data Sheet
Description
Avago Technologies’ MGA-16116 is an ultra low-noise
high linearity amplifier pair with built-in active bias and
shutdown features for balanced applications in the 900
MHz band. Shutdown functionality is achieved using a
single DC voltage input pin.High linearity is achieved
through the use of Avago Technologies’ proprietary GaAs
Enhancement-mode pHEMT process ^[1]. It is housed in a
miniature 4.0 x 4.0 x 0.85 mm 16-pin Quad Flat No-lead
(QFN). The compact footprint coupled with ultra low noise
and high linearity makes MGA-16116 an ideal choice for
basestation transmitters and receivers.
For applications > 1450 MHz, it is recommended to use
MGA-16216 1440-2350 MHz or MGA-16316 1950-4000
MHz. All 3 products share the same package and pin out
configuration.

• Ultra low-noise RF amplifiers.
Notes:
1. Enhancement mode technology employs positive Vgs, thereby
eliminating the need of negative gate voltage associated with
conventional depletion mode devices.
2. Measured at RFin pin of packaged part, other losses deembedded.
3. Good RF practice requires all unused pins to be grounded.
Attention: Observe precautions for
handling electrostatic sensitive devices.
