The LEE1-84+ is a high-linearity gain block amplifier in a low-cost surface mount package, fabricated using an InGaP/GaAs HBT semiconductor process. Operating from DC to 4000 MHz, this amplifier features high dynamic range with typical 5 dB noise figure, 19.1 dB gain, +20.9 dBm P1dB, and +35 dBm OIP3 at 2 GHz. This combination of performance makes it ideal for sensitive, high dynamic range receiver applications. The LEE1-84+ operates on a single +5 V supply and consumes 108 mA, is well matched to 50Ω, and comes in a small, low-profile 1.5×1.5 mm QFN-style package for ease of integration into dense circuit board layouts.
