The MRFIC1501 is a low cost yet high performance two–stage, low–noise amplifier designed primarily for use in Global Positioning Satellite System (GPS) and other L–band satellite receivers. The broadband nature of the design makes the device applicable to a variety of L–band applications where high performance at reasonable current and cost are required. Supply current is minimized through a current sharing DC cascode circuit configuration. Supply voltage can be applied to either the VDD pin or the RF output pin for remote antenna applications. The integrated circuit requires minimal off-chip matching while allowing for maximum flexibility in optimizing gain and noise figure. An ENABLE pin is provided to allow for a reduced supply current standby mode. The design employs Motorola’s low cost planar self–aligned MESFET process to assure repeatable characteristics at minimal cost.
