The stand-out points about the aforementioned device include (http://newsroom.sprint.com/blogs/devices-apps-and-services/htc-one-rocks-out-with-fresh-new-design.htm) HTC BoomSound with dual stereo speakers in the front and a balanced amplifier
boost bass guaranteeing crystal clear vocals/tracks.

topology," 4th Symposium Quality Electronic Design (ASQED), 86-90, Sep.
Also, the proposed quadrature power divider has been utilized to design a balanced amplifier
whose measured results show that a balanced amplifier
with FBW of 124.4% has been successfully implemented.
A new GaAs dual low noise amplifier (LNA) that combines high gain and state-of-the-art noise figure with high IP3 performance and is ideal for balanced amplifier
use has been introduced.
In a balanced amplifier
, DC should not occur across the differential output signal (Vout+) - (Vout-) but it does.
If one half of a balanced amplifier
fails, it will still operate with a gain reduction of about 6 dB.
This filter is followed by a balanced amplifier
and then another bandpass filter with a very narrow bandwidth that is designed to optimize group delay performance for rejection of the remaining close-in spurious signals without introducing data loss.
The balanced amplifier
was then designed by incorporating single-ended amplifiers between a pair of 3 dB directional couplers, as shown in Figure 12.
The output of each balanced amplifier
pair is serially combined with 3, 4.77 and 6 dB couplers to provide the assembly's full output power.
A 9 to 21 GHz broadband, high third-order intercept point (IP3), heterojunction bipolar transistor (HBT) balanced amplifier
with monolithic current regulation is demonstrated in this article.
This regulator and fault detection board is used with balanced amplifier
configurations to provide the soft-fail service.
