The F0440 400MHz to 2700MHz dual RF digital variable gain amplifier (DVGA) is designed for use in receivers. The device provides two independent receiver paths each with 11.6dB typical maximum gain and 4.7dB noise figure in the low-band configuration designed to operate with a single +5V supply. For each path Gain control is split into three separate attenuators; DSA0 is a single 6dB 步 using a single control pin, DSA1 includes 23dB SPI-controlled gain adjustment in 1dB 步s, and DSA2 includes 18dB attenuation in 6dB 步s controlled using two control pins. F0440 offers +40dBm nominal output IP3 using 245mA total ICC.
This device is packaged in a 6mm x 6 mm, 36-pin TQFN with 50Ω single-ended RF input and RF output impedances for ease of integration into the signal-path lineup for each of the two paths.
