5. Measurement
results
The evaluation board measurements are made under the following conditions, unless
otherwise stated:
•
Supply voltage V
CC
= 2.7 V
•
Power mode PAM = 3 with CASC = 0 and ENRAD = 0
•
Output amplitude AMH = 15
•
Temperature T = room temperature
•
Carrier frequency f
C
= 433.92 MHz
Detailed measurements have been performed for the 434 MHz version of the evaluation
board only.
Measurement instruments:
•
Spectrum Analyzer: Rohde & Schwarz FSP7
•
Multimeter: Agilent 34401A
The following results indicate typical values only and vary as a result of device spreads,
component tolerances or temperature changes.
