Advance Information
MH88615
AC Electrical Characteristics*
Characteristics
* Exceeding these values may cause permanent damage. Functional operation under these conditions is not implied.
Typical figures are at 25
°
C and are for design aid only.
Note 1: All of the above test conditions use a test source impedance which matches the device’s impedance.
Note 2: THD is measured with “A Weight” filter.
AC Electrical Characteristics*- MH88615-1
Characteristics
* Exceeding these values may cause permanent damage. Functional operation under these conditions is not implied.
Note:
Return Loss reference impedance are defined by variant type.
Transhybrid Loss is measured when terminated with network impedance.
AC Electrical Characteristics*- MH88615-3
Characteristics
* Exceeding these values may cause permanent damage. Functional operation under these conditions is not implied.
Note:
Return Loss reference impedance are defined by variant type.
Transhybrid Loss is measured when terminated with network impedance.
