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
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 optionsto 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
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
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.
