General Description

The CMA-252LN+ amplifier is fabricated using E-PHEMT technology and offers extremely high dynamic

range with ultra low noise figure and good input and output return loss. Terminal finish is Ni-Pd-Au and

it has repeatable performance from lot to lot due to fully automated, tightly controlled semiconductor and

assembly processes.

Typical Applications

• Base station infrastructure

• Satellite Communication (Inmarsat)

• LTE

• GPS

• Tactical Air Navigation
