General Notes:
1. The PDF-4A-100 4-way Power Di-
vider/Combiner covers a broad frequency
range of 1 to 200 MHz using a lumped element
design to reduce the size to an absolute mini-
mum. This unit is ideal for applications where
high performance and low profile are essen-
tial.
2. Higher performance, including better isola-
tion and lower insertion loss, is available with
the PDF-4E series of Four Way Power Di-
vider/Combiner. These units are supplied in a
larger package than the PDF-4A-100.
3. Other Merrimac Power Dividers/Combiners
are available for frequencies from a few kilo-
hertz to 20 GHz, with outputs from two to
sixteen and for powers up to several kilowatts.
NOTES:
1. Tolerance on 3 place decimals
±
.010(.25) except as noted.
2. Dimensions in inches over millimeters.
3. Dimensions marked with * apply only at body.
4. All unmarked pins are case ground.
