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.
