The LEE1-63+ is high-linearity gain block amplifier in a low-cost surface mount package fabricated using an InGaP/GaAs HBT semiconductor process. Operating from DC to 6000 MHz, this amplifier features high dynamic range with typical 3.4 dB noise figure, 19.5 dB gain, +16.6 dBm P1dB, and +30 dBm OIP3 at 3 GHz. This combination of performance makes it ideal for sensitive, high dynamic range receiver applications. The LEE1-63+ operates on a single +5 V supply and consumes 69 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.
