F0448 - Dual Matched Broadband RF DVGA

Datasheet Summary

Description

The F0448 is a 3.4GHz to 3.8GHz dual RF digital variable gain amplifier (DVGA) designed for use in 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.

Features

  • RF Frequency Range: 3.4GHz to 3.8GHz.
  • Dual Channel RF amp and DSAs for Diversity / MIMO Receivers.
  • < 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.
  • +37dBm OIP3 at 3.6GHz.
  • 6dB Noise figure at 3.6GHz.
  • +5V Supply voltage.
  • ICC = 220mA.
  • Independent standby: 7mA standby current.
  • SPI interface for DSA1.

Dual Matched Broadband RF DVGA 3.4GHz to 3.8GHz F0448 Datasheet Description The F0448 is a 3.4GHz to 3.8GHz dual RF digital variable gain amplifier (DVGA) designed for use in 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 ICC.
