GaN C- to X-band Quasi-MMIC High Power Amplifiers
MEC has successfully designed GaN-based Quasi-MMIC HPAs for different customers.
Their characteristics are:
- GaN Power Bars (can be chosen from different vendors) + MMIC passive only matching networks
- Full-matching (to the system reference impedance)
- Easy DC to RF decoupling
- Very Compact dimension compared to Hybrid Pallet Amplifiers
- Broader frequency bandwidth compared to Hybrid Pallet Amplifiers
- Suitable to be integrated in very compact SSPA schemes
- Lower Cost compared to full MMIC
- Faster Time to Production compared to full MMIC
Typical achieved performance on previously designed Quasi-MMIC HPAs at X-band.

GaN X-band 3-stage Solid State Pallet Amplifier
Example of complex 3-stage SSPA exploiting
- 1st Stage: 1 x MECXQMM-20W Quasi-MMIC PA
- 2nd Stage: 3 x MECXQMM-20W Quasi-MMIC HPAs
- 3rd Stage: 3 x MECXQMM-50W Quasi-MMIC HPAs
combined in a very small area. Peak output power of 140W with 30% overall PAE can be achieved in a 15% relative bandwidth at X band.
