Table 4. Power Amplifier Performance Specifications
Unless otherwise specified nom specs apply to the nom conditions in attribute and the max and min conditions are
defined by the process and other spec limits that give these worst case corners.

Measured at the line
impedance. The 4 to 1
transformer must have total
harmonic distortion better
than 50dB over 30kHz < f <
550kHz.
The multi-tone spec is the
important spec. The two tone
specs exist because the test
equipment may not be able to
create a good enough multi-
tone input signal.
