Description The HMMC-5027 is a broad- band GaAs MMIC traveling wave amplifi er designed for medium output power and moderate gain over the full 2 to 26.5 GHz frequency range. Seven MES-FET cascode stages pro- vide a fl at gain response, making the HMMC-5027 an ideal wideband power block. Optical lithography is used to produce gate lengths of ≈0.5 µm. The HMMC-5027 incorprates advanced MBE technology, Ti-Pt-Au gate metal- lization, silicon nitride passivation, and polyimide for scratch protection.
