In this letter, the first packaged THz solid-state amplifier operating at 0.85 THz is reported. The InP HEMT amplifier achieves a noise figure as low as 11.1 dB with an associated gain of 13.6 dB at 0.85 THz using high InP HEMT transistors in a 10-stage coplanar waveguide integrated circuit. Output power up to 0.93 mW is measured.
In this work, we describe recent advances in InP HEMT and InP HBT technologies that have led to circuits approaching 1 THz. At lower frequencies, these technologies have demonstrated record performance in terms of noise figure (NF), output power, or power-added efficiency (PAE). On the other hand, CMOS-based technologies are dominating semiconductor industry, because they offer high complexity, yield,...
In this paper, a 220 GHz solid-state power amplifier (SSPA) module is presented. Eight-way on-chip power combining is used to achieve a saturated output power ≥ 50 mW over a 217.5 to 220 GHz bandwidth, representing a significant increase in SSPA output power at this frequency compared to prior state of the art. The amplifier MMIC is implemented in coplanar waveguide (CPW) technology and uses sub 50...
