F0448

Datasheet

Description

Features

The F0448 is a 3.4GHz to 3.8GHz dual RF digital variable gain

amplifier (DVGA) designed for use in receivers.

RF Frequency Range: 3.4GHz to 3.8GHz

Dual Channel RF amp and DSAs for Diversity / MIMO

Receivers

This dual RF DVGA provides two independent receiver channels

each with 13dB typical maximum gain and 6dB noise figure

designed to operate with a single +5V supply. For each channel,

gain control is split into three 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. The

F0448 offers +37dBm nominal output IP3 using 220mA total I_CC.

< 2dB overshoot between DSA transitions

13dB typical maximum gain at 3.6GHz

DSA0: Single 6dB coarse step

DSA1: 23dB total gain range in 1dB steps

DSA2: 18dB gain range in 6dB steps

6dB Noise figure at 3.6GHz

+5V Supply voltage

This device is packaged in a 6 × 6 mm, 36-QFN with 50Ω single-

ended RF input and RF output impedances for ease of integration

into the signal-channel lineup for each of the two channels.

I_CC= 220mA

Independent standby: 7mA standby current
