  KCB Signal Solutions Unveils breakthrough Envelope Tracking Solution for
  Medium Power Applications

Business Wire

BOSTON -- February 20, 2014

KCB Signal Solutions announces a new, unique envelope tracking product line
aimed at the emerging medium power RF transmitter market. The product line
will be aimed at RF transmitters that must deal with complex waveforms, such
as LTE, while transmitting between two to eight watts of average RF power.

“We were aware that multiple applications in commercial and military markets
in this power class were highly interested in envelope tracking solutions but
weren’t being served by ET suppliers involved in smartphone solutions,”
commented KCB Signal Solutions President Dave McIntosh.

The product line has been designed from the beginning to be easily scalable
due to the wide range of waveforms and output power levels it will address.
The first two variants are designed to work with 28V or 48V RF Power
transistors with other voltage options to come in future. The overall form
factor is also a key factor for this product and the footprint should be two
square inches or less depending on customer features.

McIntosh commented on the form factor by saying: “There are a number of
critical circuits that had to be developed in order to meet our performance
and form factor goals. One of the key circuits was developed through a
collaboration with Analog Devices, Inc. on their ADA4870 amplifier. ADI’s
ADA4870 is an exciting new device and its ability to efficiently work with our
high-speed current and voltage waveforms is very impressive.”

KCB Signal Solutions is delivering engineering samples to its alpha customers
in 1Q2014. Samples for the general market will become available in 3Q 2014 and
volume production support will begin in 4Q 2014.
