Abstract
- State-of-the-art 0.15- mu m-gate PHEMT (pseudomorphic high-electron-mobility transistor) devices, self-biasing current sources, source follower interstage, resistive feedback, and on-chip matching have been used to make an unique MMIC (monolithic microwave integrated circuit) LNA (low noise amplifier). Typical gain of 21 dB, VSWR (voltage standing wave ratio) of 2:1, and P-1-dB output power of 7 dBm have been measured. The die area is small (0.40 mm/sup 2/) and is compatible with surface mount packages. DC power requirements are low, consuming only 14 mA from a single +5-V supply. This MMIC LNA has the best combination of noise figure, gain. low current, match, wide bandwidth, and low cost of any advertised or published product known to the authors to date. >
