General Notes:
1. Merrimac Frequency Doublers cover
the frequency range of 5 to 3000 MHz
using lumped element circuits for broad
bandwidth and excellent rejection of
fundamental and third harmonic energy.
These units may also act as quadruplers
with additional conversion loss.
2. Merrimac Frequency Doublers comply
with the relevant sections of MIL-M-28837
and may be supplied screened for
compliance with additional specifications
for military and space specifications
requiring the highest reliability.
