This web-page is re-production of a MMIC design sheet we have assembled for our Q-band LNA project. This chip has been recently fabricated and its simulated performance is shown in this post. The chip fabrication is part of our Q-band ESA project blogged here. The low-noise amplifier has 4-stages, and it has a simulated state-of-the-art performance with low Noise Figure (NF), high gain and good broadband 50-Ω matching.
- Circuit Name: LNAFIN2, Circuit Function: Q-Band Low-Noise Amplifier (LNA).
- MMIC size: 3×2 mm2.
- Foundry: Ommic 70-nm mHemt D007IH.
Stability verification example using the gprobe2-method. Circuit response is stable in all
loading conditions when probed values remain within -1. . . +1.
Simulated Performance Table
|Output 1-dB compression||dBm||4|
|Input return loss||dB||22.4|
|Output return loss||dB||21.9|
|DC power consumption||mW||153.6|
|Operating temperature||°C||-25 to +75|
|PORT1 bw RL=18 dB||GHz||14.8|
|PORT2 bw RL=20 dB||GHz||66.1|
Note: linearity (1-dB compression) is limited by the small-signal models, which have
only few biasing points. We have done the large signal simulations with biasing points, which correspond to tabulated small-signal characteristics.
