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.
