BGA771N16 - Low Power Dual-Band UMTS LNA
Description
1
Description
The BGA771N16 is a highly flexible, high linearity dual-band (1900/1800/2100, 800/900 MHz) low noise amplifier
MMIC for worldwide use. Based on Infineon’s proprietary and cost-effective SiGe:C technology, the BGA771N16
uses an advanced biasing concept in order to achieve high linearity.
The device features dynamic gain control, temperature stabilization, standby mode, and 2 kV ESD protection on-
chip as well as matching off chip. Because the matching is off chip, different UMTS bands can be easily applied.
For example, the 1900 MHz path can be converted into a 1800 MHz or a 2100 MHz path by optimizing the input
and output matching network.
Note: UMTS bands II / V is the standard band combination for this product requiring no external output matching
network.
Features
• Gain: 16 / -7.5 dB in high / low gain mode (all bands)
• Noise figure: 1.1 / 1.1 dB in high gain mode
(800 MHz / 1900 MHz)
• Supply current: 3.4 / 0.65 mA in high / low gain mode (all bands)
• Standby mode (< 2
µA
typ.)
• Output internally matched to 50
Ω
• Inputs pre-matched to 50
Ω
• 2kV HBM ESD protection
• Low external component count
• Small leadless PG-TSNP-16-1 package (2.3 x 2.3 x 0.39 mm)
• Pb-free (RoHS compliant) package
