This limitation has been a barrier to receiver performance in lower frequency applications. Breaking through that barrier would require a MMIC amplifier with the holy trinity of low noise, high IP3, and multi- octave frequency range without multiple, band-specific matching circuits. Raising the Standard for Combined Performance To better support system designers working at the lower end of the frequency spectrum, Mini-Circuits developed a new series of MMIC amplifiers utilizing 0.5 micron E/D mode PHEMT process on GaAs, spanning bandwidths as wide as 1000:1 from 1 MHz up to 2 GHz. These designs employ a proprietary architecture enabling good matching down to 1 MHz without any band- specific matching circuits, which is highly unique for PHEMT designs. These amplifiers raise the industry benchmark for combined performance, combining all the key features for broadband, high- dynamic range receivers in the HF, VHF, and UHF application bands: They are well matched for 50Ω without any band-specific matching circuits required.
