F0440
Datasheet
Description
This document describes the specifications for the F0440
600MHz to 2700MHz Dual RF Digital Variable Gain Amplifier
designed for use in receivers.
F0440 Dual RF DVGA provides two independent receiver paths
each with 11.6dB typical maximum gain and 4.7dB noise figure in
the lowband configuration designed to operate with a single +5V
supply. For each path Gain control is split into 3 separate
attenuators; DSA0 is a single 6dB step using a single control pin,
DSA1 includes 23dB SPI-controlled gain adjustment in 1dB steps,
and DSA2 includes 18dB attenuation in 6dB steps controlled
using two control pins. F0440 offers +40dBm nominal output IP3
using 245mA total ICC.
This device is packaged in a 6mm x 6mm, 36-pin TQFN with 50
ohm single-ended RF input and RF output impedances for ease
of integration into the signal-path lineup for each of the two paths.
