F0440 Dual Matched Broadband RF Datasheet DVGA 450MHz to 2700MHz Description Features This document describes the specifications for the F0440 Dual Path RF amp & DSAs for Diversity / MIMO Receivers 450MHz to 2700MHz Dual RF Digital Variable Gain Amplifier RF: 450MHz to 2700MHz designed for use in receivers. < 2dB overshoot between DSA transitions 11.6dB typical max gain 900MHz F0440 Dual RF DVGA provides two independent receiver paths each with 11.6dB typical maximum gain and 4.7dB noise figure in DSA0 is a single 6dB coarse step the low-band configuration designed to operate with a single +5V DSA1 has 23dB total gain range in 1dB steps supply. For each path Gain control is split into 3 separate DSA2 has 18dB gain range in 6dB steps attenuators DSA0 is a single 6dB step using a single control pin, +41dBm OIP3 2000MHz DSA1 includes 23dB SPI-controlled gain adjustment in 1dB steps, 4.7dB Noise Figure 900MHz and DSA2 includes 18dB attenuation in 6dB steps controlled +5V Supply Voltage using two control pins. F0440 offers +40dBm nominal output IP3 using 245mA total ICC. ICC = 245mA Independent standby: 7mA standby current This device is packaged in a 6mm x 6mm, 36-pin TQFN with 50 SPI interface for DSA1 ohm single-ended RF input and RF output impedances for ease 1-bit control for DSA0 of integration into the signal-path lineup for each of the two paths. 2-bit control for DSA2 Competitive Advantage 50 input and output impedance Broadband, Internally Matched High Reliability 6mm x 6mm, 36-pin TQFN package High Linearity Low DC current TM Zero Distortion technology Block Diagram TM GlitchFree technology Figure 1.
