M53357P DIP IC

Intermodulation intercept points are measured with
two equal amplitude input signals spaced closely
together in frequency. Since MESFETs are non-linear
devices, they exhibit ?mixing? or frequency-generation
characteristics. In any kind of receiving system,
signals that are generated internal to the device can
degrade overall system performance. This
measurement is used to determine the intercept
points (typically second and third order) of a device.
The intercept points are calculated values and are
defined as the power at which the intermodulation
product amplitude is equal to the input. This quantity
plays a major role in system dynamic range and
sensitivity performance. The intercept points are
calculated as follows:
IPn = [IMDn/(n-1)] + Pin
Where: IPn = nth order intercept point (dBm)
IMDn = nth order intermodulation distortion
product (dBc)
n = order
Pin = input power (dBm)
