UMS develops the CHA8254-99F, a three-stage GaN Doherty Power Amplifier in the 17.3‑20.3GHz frequency band. This DPA typically provides 10W of output power associated with 31% of Power Added Efficiency. Thanks to Doherty architecture, it also provides 27% Power Added Efficiency at 6dB of input back-off (around 3dB of output back-off). The small signal gain exhibits more than 29dB. The overall power supply is 15V/225mA (quiescent current). Thanks to a low drain voltage biasing, the CHA8254-99F provides a junction temperature below 160°C even in saturation.
This circuit is a very versatile amplifier for high performance systems.
The circuit is dedicated to space applications and also well suited for a wide range of microwave applications and systems.
The part is developed on a robust 0.15µm gate length GaN-on-SiC HEMT process and is available as a bare die.
UMS develops a High Power Frond-End (HPFE) featuring Transmit and Receive paths combined with In/Out Switch. This circuit operates in the 24.25-30.5GHz bandwidth. It is specially designed for telecommunication radio links. It typically exhibits a Receiver gain of 18dB with a low noise figure of 3.2dB, a Transmit gain of 28dB with 31dBm saturated output power. It features good linearity with an ACPR of 36dBc @23dBm average Pout with 56MHz modulation bandwidth and 4QAM.
This HPFE is realized on mixed technologies 150nm Gallium Nitride on Silicon Carbide (AlGaN/GaN on SiC) and 150nm Gallium Arsenide (GaAs) - UMS proprietary technologies - and provided in a cost effective plastic package.
