Notes:
The allowable ambient temperature range specied is based on the module mounted to a
50 x 50 mm 2-signal/2-power plane card with the specied airow on both sides of card, vertical
orientation.
S420 can also be operated at 60 MHz with an increase in power of less than 5%. This does not
change the application conditions shown in this table.

Notes:
The allowable ambient temperature range specied is based on the module mounted to a
50 x 50 mm 2-signal/2-power plane card with the specied airow on both sides of card, vertical
orientation.
The operating range is show for reduced search range (+/- 64 H, +/- 56 V) operation.
For the reduced search conguration, S420 should only be operated at 57 MHz in order to meet
the application conditions shown in this table.
