Transmitters & Receivers

We develop high-performing transmitters and receivers for the mobile communication technologies of the future (5G, 6G), sensor as well as radar applications.

Intelligent transmitters

The needs of wireless communications in the 5G and 6G era are characterized by high bandwidth requirements, MIMO architectures and carrier frequencies in the mm-wave range. For this purpose, frequency-agile and software-defined hardware is required, all this under the constraint of low energy consumption (GreenICT). There are significant synergies with the hardware needed for the so-called digital radar. We, at FBH, address these demands with new transmitter concepts based on digitization of analog functions and switching.

Load & Supply Voltage Modulation

envelope tracking, floating ground transistors, discrete level supply modulation, reverse buck converter, floating ground transistors, high-power SSPAs, wideband supply modulators

Digital Transmitters

GaN- & AlN-based VHF DC/DC converter, GaN-based digital Tx, digital CMOS handset Tx, intelligent phased-array sub-THz Tx

High dynamic range receivers

III-V devices offer inherently higher breakdown voltages than their Si-based counterparts. This allows to realize components with higher dynamic range, which is essential for many applications, from communication receiver frontends to sensing and radar.

Robust GaN low-noise Amplifiers

GaN-HEMT based LNAs, ultra-robust designs, single-chip transceivers, demonstration of AlN-HEMT LNAs

X-Band GaN Mixers

GaN-based X-band mixers in cooperation with Technical University of Denmark - DTU, fully-integrated GaN-mixer-MMICs, highly-linear mixers
