Ultra Low Phase Noise Amplifiers
Hittite Microwave Corporation introduces the broadband, ultra low phase noise distributed MMIC amplifiers, which are suitable for military, space, test equipment and fiber optic applications from 2 to 18 GHz. The HMC606 and HMC606LC5 are GaAs InGaP HBT MMIC distributed amplifiers, which deliver a typical small signal gain of 13.5 dB, and input and output return losses of 20 dB at mid-band. These amplifiers deliver phase noise performance, which represents an improvement over equivalent FET-based distributed amplifiers. Measured with a ם dBm input signal at 4 GHz, the HMC606 and HMC606LC5 exhibit good phase noise performance of 𤪉 dBc/Hz and 𤪍 dBc/Hz at 1 kHz and 10 kHz offsetrespectively.
