ALM-81224

High Linearity 1450-2750 MHz Variable Gain Amplifier

Currently Viewing:

ALM-81224 is a high linearity variable-gain amplifier module for use in the 1450-2750MHz band.

Gain control is achieved using a single DC voltage input pin, and High linearity is achieved through the use of Broadcom's proprietary GaAs Enhancement-mode pHEMT process.

Features

  • High Linearity at low bias current
  • High max gain: 23.8 dB typ
  • High Linearity performance
  • Fully-matched 50 Ohm input and simple output match
  • Low Noise Figure
  • Built-in attenuator with monotonic response

Applications

  • Basestation Transmitter, Receiver and Temperature Compensation Circuits requiring continuously variable gain functionality
