3 to 10 W Solid-State Power Amplifiers for K- and Ka-Band

February 14, 2019

To support the development of 5G, SATCOM and other applications at K- and Ka-Band, Exodus Advanced Communications offers four solid-state power amplifiers (PA) with 3 to 10 W output at 1 dB compression and 37 to 40 dB power gain. All are class A/AB designs using GaAs FETs.

The AMP4065LC-2 delivers 10 W minimum across 18 to 26.5 GHz. At rated power, the two-tone intermodulation products are −30 dBc typical, harmonics −20 dBc maximum and spurious better than −60 dBc. The 3U rack-mountable unit is cooled with forced air. Liquid cooling is an option, yielding a smaller and quieter amplifier.

The AMP4066-2 delivers 10 W at 1 dB compression across 26.5 to 40 GHz, with similar harmonic and spurious performance. The standard amplifier is also housed in a 3U, 19 in. rack chassis and cooled with forced air, with liquid cooling an option.

The AMP4047 and AMP4047A provide 3 W at 1 dB compression across 18 to 26.5 GHz and 26.5 to 40 GHz, respectively. Intermodulation, harmonic and spurious are similar to the AMP4065LC-2. This PA is housed in a 2U benchtop chassis and uses fan cooling.

The AMP4065LC-2 and AMP4066-2 models include a color touch screen and controller supporting Ethernet TCP/IP, USB, RS422 or RS485 interfaces; GPIB and Bluetooth are options. The AMP4047 does not have the touch screen, since it was developed as a basic benchtop PA for applications not requiring remote control.

The 10 W PAs can replace TWTAs for EMI/RFI susceptibility, communications and test systems. Exodus Advanced Communications offers other power levels within these families, as well as amplifiers from 10 kHz to 51 GHz - 70 GHz being developed - and power levels to multi-kW, depending on frequency.
