Very low-current and small-size GaAs MMICs for L-band front-end applications

Very-low-current and small-size GaAs MMICs (monolithic microwave integrated circuits) were developed for L-band front-end applications. The MMICs fully employ lumped LC elements with uniplanar configurations. There are two kinds of MMICs: a low-noise amplifier and a mixer. The low-noise amplifier has a noise figure of 2.5 dB and a gain of 11.5 dB. The mixer has a conversion gain of 12.5 dB with small LO power of -3 dBm. Total current dissipation of the two MMICs is less than 8 mA with 3-V drain bias voltage. >
