Features and Benefits

  • P1dB Output Power: +12 dBm
  • Gain: 25 dB
  • Noise Figure: 3 dB @ 25 GHz
  • Supply Voltage: +2.5V @ 52 mA
  • Die Size: 1.80 x 0.73 x 0.1 mm

Product Details

The HMC-ALH311 is a GaAs MMIC HEMT Low Noise Driver Amplifier die which operates between 22 and 26.5 GHz. The amplifier provides 25 dB of gain, a typical noise figure of 3 dB at 25 GHz, and +12 dBm of output power at 1 dB gain compression while requiring only 52 mA from a +2.5V supply voltage. The HMCALH311 is ideal for microwave radio driver amplifier applications between 22 to 26.5 GHz. Due to its small size, the HMC-ALH311 die is ideal for integration into Multi-Chip-Modules (MCMs).

Tools & Simulations


Sys-Parameter Models for Keysight Genesys

Sys-Parameter models contain behavioral parameters, such as P1dB, IP3, gain, noise figure and return loss, which describe nonlinear and linear characteristics of a device.

Design Tool


ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.

Design Resources
