Skyworks Introduces New High Linearity, Active Bias,
Low Noise Amplifier for Cellular Infrastructure
|
 
WOBURN, Mass., Dec. 20, 2013
 Skyworks
Solutions, Inc. has introduced a 0.7-1.2 gigahertz, single-die cascode, gallium arsenide (GaAs), pseudomorphic high
electron mobility transistor (pHEMT) low-noise amplifier (LNA) for cellular infrastructure applications such as
tower-mounted amplifiers, remote radio units, repeaters, and base stations. The new LNA offers very low noise figure
and high linearity along with excellent return loss and gain flatness in a small 2x2 mm, no lead plastic package.
On-die active bias design of the SKY67111-396LF ensures consistent performance and enables unconditional stability
with a 5 V supply. The rugged cascode design achieves nearly 19 dBm IIP3, 0.5 dB noise figure, and >20 dB
gain. The bias circuit allows the device current to be set independently from the Vdd supply, enabling optimal efficiency
for a wide range of applications.
This amplifier solution is ideal for wireless infrastructure OEMs
having receiver applications that require highly efficient amplification with high gain and flat gain response.
In addition, its exceptional linearity makes the part an excellent linear amplifier for transmitter applications.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
