D. Find suitable P/N on Web Catalog List
|
|
There are 7 step to help use Web Catalog List and find out
the most closed P/N you need.
|
|
|
Step 1: choose one series where can meet your requested Fo
ex: 7H (42~1500M) or 5W(230~2600M ) |
 |
|
|
|
|
|
Step 2:choose one attenuation level, normally, 3 pole is enough.
ex: 7H3, 5R3, 5W3, etc. |
 |
|
|
|
|
|
Step 3: choose the range where your requested Fo is
ex: 7H3-1 (42~355), 7H3-2 (355~750), 7H3-3 (750~1500),etc |
 |
|
|
|
|
|
Step 4:looking for "Accept
Frequency Range" where your requested Fo is.
ex:
"Requested Fo =460M" is in "Accept
Frequency Range=456~515M". |
 |
|
|
|
|
|
|
Step 5: under the same "Accept
Frequency Range", choose the suitable BW
ex: under "Accept
Frequency Range=456~515M", you have BW= 8M,15M,26M,
30M,40M,50,60M,80M,90M,120M,etc for you to pick. |
 |
|
|
|
|
|
Step 6: under the same "Accept
Frequency Range" and suitable "BW",
choose the suitable IL, Pin Position & Attenuation
ex: under "Accept
Frequency Range=456~515M", you have IL= 3.0, 2.0,1.0, etc for you to pick.
ex: under "Accept Frequency Range=456~515M", you have Pin position=B, E, F type for you to pick.
ex: under "Accept Frequency Range=456~515M", you can evaluate the attenuation value of
(Fo+/-50Mhz) , (Fo+/-100Mhz), (Fo+/-16Mhz), (Fo+/-30Mhz), etc. |
 |
|
|
|
|
|
Step 7: Compare all spec point (Fo, BW, IL, Attenuation),
then choose the most closed P/N
ex: TT63232E-490M |
 |
|
|
|
|
|
|
Note:
1. All Fo (Center Frequency) can be set into any point of frequency during
"Accept Frequency
Range".
2. All P/N can change PIN POSITION from "A,
B,
C,
D,
E,
F type" to
"A,
B,
C,
D,
E,
F
type"
under a tiny spec change.
3. If you need to customized BW, IL, Attenuation, please contact with us directly.
