TQM879026 - Digital Variable Gain Amplifier

Description

The TQM879026 is a digital variable gain amplifier (DVGA) featuring high linearity and digital variable gain control in 0.5 dB step sizes.

This DVGA integrates a gain block, a digital-step attenuator (DSA), and a high linearity ¼-watt amplifier into a compact 4x4 mm package.

Features

  • 0.7-4.0 GHz Frequency Range.
  • 32 dB Maximum Gain at 2.14 GHz.
  • 31.5 dB Gain Range in 0.5 dB Steps.
  • +42.5 dBm Output IP3.
  • +24 dBm Output P1dB.
  • 1.6 dB Noise Figure.
  • 3-wire SPI Control Programming General.
