Next-generation broadband satellite systems require exceptionally linear and high-power RF links to support “anywhere, anytime” connectivity. mmTron’s TMC215 MMIC power amplifier (PA) extends the linear power benchmarks for Ka-Band satcom. Covering 27 to 31 GHz, the TMC215 delivers 45 W of output power at 1 dB compression (P1dB) with 34 percent power-added efficiency (PAE).
In linear operation, the PA achieves –32 dBc spectral regrowth at 25 W output and a 21 dBc noise power ratio (NPR) at 22 W. With a 5G NR signal, the error vector magnitude (EVM) remains below 3 percent up to an output power of 10 W, and the adjacent channel leakage ratio (ACLR) exceeds –40 dBc. The three-stage architecture provides 23 dB linear gain.
The TMC215 is typically biased at 28 V drain voltage and 3 A current draw. To support flexible system integration, the drain bias can be reduced to 18 V, enabling power scaling while maintaining linearity and PAE.
Built using space-qualified GaN-on-SiC technology, the TMC215 was engineered for demanding environments. The transistor layout, matching networks and backside metallization were optimized for high reliability. When assembled according to mmTron’s guidelines, the mean time to failure (MTTF) exceeds 107 hours at a junction temperature below 210°C.
The amplifier is available as bare die (4.9 × 4.0 × 0.1 mm), die-on-tab (CuMoCu, CuW or Ag-Diamond) with bypass capacitors or in a flange package. An evaluation module is also available for prototyping and testing.
The TMC215 is just one of mmTron’s high-linearity, high-power MMICs that cover frequency bands between 22 and 42 GHz. Datasheets are available at mmtron.com/products/.
