The F0448 is a 3.3GHz to 4.2GHz dual RF digital variable gain amplifier (DVGA) designed for use in receivers. This dual RF DVGA provides two independent receiver paths each with 13dB typical maximum gain and 6dB noise figure designed to operate with a single +5V supply. For each path, gain control is split into 3 separate attenuators; DSA0 a single 6dB step using a single control pin, DSA1 a 23dB SPI-controlled gain adjustment in 1dB steps, and DSA2 includes 18dB attenuation in 6dB steps controlled using two control pins. F0448 offers +37dBm nominal output IP3 using 220mA total I_CC. This device is packaged in a 6mm x 6mm, 36-QFN with 50Ω single-ended RF input and RF output impedances for ease of integration.
