Hillsboro, Ore. and Richardson, TexasRFIC house TriQuint Semiconductor , is poised to roll out two high-OTOI (output third-order intercept) GaAs (gallium arsenide) PA s (power amplifiers). These PAs promise to be smaller, lower-cost alternatives (compared to previous-generation products).
The TGA4530s will be able to be used for coverage of 17-GHz through 21-GHz for applications. They will be available in both MMIC (monolithic microwave IC) form-factors, and in industry-standard plastic surface-mount packages.
TriQuint's TGA4530 and TGA4530-SM devices are designed for point-to-point radio, K-band satellite communications, and point-to-multi-point network applications. The TGA4530 is a MMIC version; the TGA4530-SM is packaged.
In either case, these devices tout OTOI performance that ensures higher data rates, improved system efficiency, and longer range transmissions. These RFICs will also include an on-chip power detectors. That can reduce a BOM (bill of materials). They will also include protective surface passivation layers.
A TGA4530 provides 42-dBm OTOI, and 30-dBm (1-W) output power (at the 1-dB compression point at a bias of 7-V; 825-mA Idq ). Typical gain is 20-dB, with input and output return losses of 15-dB.
The MMIC's small size is achieved using TriQuint's 0.25-micron power pHEMT 3MI (3-metal-layer interconnect pseudomorphic high electron-mobility transistor) production process.
Evaluation boards are available; these products are lead-free and RoHS -compliant (Restriction of Hazardous Substances in Electrical and Electronic Equipment).
