Board Mounting Type (DC to 8.0 GHz)
ꢀMounting Method
AT-900 Type
Make the AT-900 tab height from the housing and the
ꢀ
thickness of the microstrip board the same amount.
The tabs are attached with high temperature solder (having
ꢀ
a melting point of 280ç). The soldering temperature to the
microstrip board must be less than this.
AT-900-C Type
The case and ground electrodes are attached with high
ꢀ
temperature solder (having a melting point of 240ç). The
soldering temperature to the housing (ground) must be less
than this.
The 50ø line and the center electrode of the AT-900-C are
ꢀ
soldered with the tabs, and mounting is by bonding using
gold wire, etc.
Soldering should be performed quickly so that diffusion of
ꢀ
the center (gold) electrode does not occur.
97
Board Mounting Type (DC to 8.0 GHz)
AT-900-T Type
The 50ø line and the center electrode of the AT-900-T are
ꢀ
soldered with the tabs, and mounting is by bonding using
gold wire, etc.
Soldering should be performed quickly so that diffusion of
ꢀ
the center (gold) electrode does not occur.
AT-900-PT Type
The ground of the resistor surface and the ground of the
ꢀ
rear surface are not connected when a single AT-900-PT
is used. To maintain the high frequency characteristics, the
board should be processed or a mounting arrangement
provided so that the ground of the resistor surface and the
housing (ground) conduct.
When making connection by soldering with the tabs,
ꢀ
soldering should be performed quickly so that diffusion of
the (gold) electrode does not occur.
