mmTron Inc. has announced an up/down-converter IC for SATCOM and fixed wireless access (FWA) systems operating in frequency bands from 25 to 29 GHz.
The TMC178 is a highly integrated radio-frequency integrated circuit (RFIC) that combines a balanced mixer with a frequency tripler, filter, and pre- and post-amplifiers in the LO path. The mixer is balanced to achieve excellent isolation.
The tripler in the LO path reduces the required LO input frequency to between 6 and 8 GHz, the amplifiers enable operation with only 0 dBm input LO drive, and the built-in filter eliminates unwanted harmonics. The wide IF frequency range from 1 to 11 GHz and a single positive bias add to the RFIC’s utility.
The RFIC’s performance is stable over temperature, supporting outdoor installations in all climates.
The TMC178 is available either as a bare die or in a low-cost 5 mm x 5 mm QFN package.
The highly integrated TMC178 simplifies system design and is low cost, making it well-suited for commercial Satcom and FWA applications,” said Seyed A. Tabatabaei, founder and CEO of mmTron. “It adds an important building block to mmTron’s portfolio of high linearity, high power, and high efficiency power amplifiers for mmWave systems.”
