MGA-21108
Broadband Fully Integrated Matched Low-Noise Amplifier MMIC
Data Sheet
Description
Features
Avago Technologies’ MGA-21108 is a fully integrated
GaAs Low Noise amplifier MMIC for use in the (1.5 - 8) GHz
band. Broadband performance is achieved with only one
external input matching component. Power supply chokes
and coupling capacitors are also integrated. It is housed
in a miniature (2.5 x 2.5 x 0.55) mm 8-pin STSLP package.
It includes a CMOS-compatible shutdown pin which can
also be used as a variable gain bias pin. The ease-of-use
and broadband performance make the MGA-21108 an
ideal choice as a LNA for multistandard, multiband radio
applications.
• Broadband gain with 1.4V-3.3V single-supply

Top View
• High gain : (18.7-10.7) dB at (1.5 - 8) GHz
• Low-noise : (1.5 – 2.8) dB at (1.5 -8) GHz
• Low power operation at 18mA nominal current
• Internally matched to 50 Ohm at RF output
• CMOS-compatible variable bias control and shutdown
pin
• GaAs E-pHEMT Technology[1]
• Low cost, low-profile package : (2.5 x 2.5 x 0.55) mm3
At 3.5GHz; 1.4V, 17 mA (typ) :
• 17.6 dB Gain
• 1.4 dB Noise Figure
• IP1dB : -12.3 dBm
• IIP3 : -3.3 dBm
• S11 : -6.8 dB; S22 : -7.4 dB
• Shutdown current : < 200uA
Applications
• LNA for GPS, WCDMA, IEEE 802.11g/a, 802.16e
Pin Configuration
• Low-noise 50-Ohm Gain-block
• Broadband LNA for multistandard, multiband radio
Note:
1. Enhancement-mode technology employs positive Vgs, thereby eliminating the need of negative gate voltage associated with conventional depletion mode devices.
