Radio frequency

In the world of electronic communication, there is an ever-increasing need for speed. We have a broad experience with all sorts of communication solutions, wired and wireless. We have designed complete frontend ZigBee radios for the popular 2.4GHz band, but we also work at higher bands for satellite communications, e.g. 15 GHz PLLs.

Not only have we created integrated broadband amplifiers from 400MHz to 2.7 GHz with 0.5W output power, we also develop Doherty power amplifiers with discrete LDMOS transistors up to 1 kW for 3G and LTE base stations. For all mobile applications, low-power is always a key aspect, just like low noise amplifiers for receivers.

Integrated phased array antenna system

Mobile satellite communications on planes, boats or buses require low-profile antenna systems. The antenna systems used for such applications are usually electronically steered phased arrays. A phased array antenna system is an array of antennas in which the relative phases of the respective signals received by each single antenna are delayed in such a way that the effective radiation pattern of the array is reinforced in a desired direction and suppressed in undesired direction.
