Dual Matched Broadband RF

DVGA 450MHz to 2700MHz

Datasheet

Description

Features

This document describes the specifications for the F0440

450MHz to 2700MHz Dual RF Digital Variable Gain Amplifier

designed for use in receivers.

Dual Path RF amp & DSAs for Diversity / MIMO Receivers

RF: 450MHz to 2700MHz

< 2dB overshoot between DSA transitions

11.6dB typical max gain @ 900MHz

DSA0 is a single 6dB coarse step

DSA1 has 23dB total gain range in 1dB steps

DSA2 has 18dB gain range in 6dB steps

+41dBm OIP3 @ 2000MHz

4.7dB Noise Figure @ 900MHz

+5V Supply Voltage

ICC = 245mA

F0440 Dual RF DVGA 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 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.

Independent standby: 7mA standby current

SPI interface for DSA1

1-bit control for DSA0

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.

2-bit control for DSA2

Competitive Advantage

50 Ω input and output impedance

Broadband, Internally Matched

6mm x 6mm, 36-pin TQFN package

High Reliability

High Linearity

Low DC current
