This paper reports demonstration of a 0.666 THz (666 GHz) datalink. A peak error-free data rate of 9.5 Gbps is demonstrated over a 590 m range using QPSK modulation with a measured humidity of 18% with more than 40 dB SNR at the output of the receiver. The 0.666 THz link uses InP HEMT frequency converters providing both low noise and power amplification, a traveling wave tube Amplifier, and an advanced...
Northrop Grumman has extended its development of compact, microfabricated vacuum electronic amplifiers to 1.0 THz. Most recently, our 1.030 THz amplifier produced 29 mW at 1.03 THz with 20 dB of gain at saturation and 5 GHz of instantaneous bandwidth. The compact power amplifier is based on an electroplated, Si-DRIE folded waveguide slow-wave circuit, together with a high current density thermionic...
Northrop Grumman Electronic Systems has developed the first, compact, microfabricated vacuum electronic amplifier operating at 0.835–0.875 THz. The amplifier produced >50 mW of output power at the window at frequencies between 0.835–0.842 THz and 39.4 mW of output power at 0.850 THz. The amplifier exhibited 26 dB of small signal gain and 11 GHz of instantaneous bandwidth. The compact power amplifier...
A 220 GHz power amplifier has been demonstrated as part of the DARPA HiFIVE program. This amplifier is based on a folded waveguide circuit, and operates at 19 kV and 250 mA. Short pulse tests resulted in 56 W at 214 GHz and a 5.0 GHz bandwidth.
Northrop Grumman Electronic Systems is developing vacuum-based power amplifiers operating at G-band with over 50W of output power and 3.5 GHz bandwidth. New power module configurations using a single electron beam, compact solenoidal magnet, and integrated power conditioner are being developed for system integration on airborne platforms.
A 0.670 THz Power Module based on a vacuum electronic (VE) power amplifier and a solid-state power amplifier (SSPA) has produced >100 mW, operating from 0.640–0.685 THz in a bread-board demonstration. The driver amplifier is a power-combined, MMIC SSPA module based on InP HEMT technology. The compact VE power amplifier is based on a DRIE-fabricated folded waveguide slow-wave circuit, together with...
