Empower launches single-band GaN amplifiers for product testing at 600-6000MHz.

Empower RF Systems Inc of Inglewood, CA and Holbrook, NY, USA (which produces RF and microwave power amplifiers for defense, commercial and industrial applications) has launched single-band gallium nitride (GaN) ultra-broadband microwave amplifiers for product testing at 600-6000MHz.

Equally suitable for the production floor, engineering lab or anechoic chamber, the model 2223 comes complete with internal DDC (direct digital controller), external forward and reverse sample ports, and an easy-to-use web-served graphical user interface (GUI). In-depth health monitoring with alarms visible on the front panel are also pushed out the LAN port. Output modes include manual gain control, automatic gain control (AGC) and automatic level control (ALC), which provide useful flexibility when integrating into product testing applications.

The model 2222 produces 50W of power across the same band and is suitable for conducting testing with any modulation scheme (CW/pulse/OFDM/AM/FM/multi-tone). For complex digital modulations, you set the PAR (peak to average ratio) and the amplifier will meter and report the output power accurately – a suitable choice for the ‘handy transmitter’ ISO 11452-9 test.

For embedded applications Empower RF offers more bandwidth with the 1219 module – 500-6000MHz in a single-band solid-state 48VDC GaN compact module. Delivering a minimum 25W (40W typical), Empower RF claims to be the first amplifier manufacturer to cover this bandwidth with an affordable commercial off-the-shelf (COTS) product.

The 1219 utilizes 50V gallium nitride on silicon carbide (GaN-on-SiC), which is the most robust GaN technology available. GaN-on-SiC technology has lower leakage currents and higher thermal conductivity and is known to be a more reliable technology than GaN. An added benefit is that 50V devices require about half the input current of their 28V counterparts, offering the benefit of reduced external power supply size and weight.

Empower RF Systems is exhibiting in booth #201 at the 2019 IEEE EMC Symposium in the New Orleans Ernest N Morial Convention Center (22–26 July).
