RF Reference Design Data

Freescale Semiconductor

MRFE6VP61K25H MRFE6VP61K25HS 2 Meter Amateur

PERFORMANCE AND RF MEASUREMENTS

Measurement is done using a CW (single tone) signal

unless specified otherwise.

Data was taken using an automated characterization

system, ensuring repeatable measurements.

The reference design was tuned with a trade--off between

linearity and efficiency. Other tuning optimizations are

possible.
