Ordering information

Example configuration: 

A test system is being built
that requires the following
Microwave Switching:

• (qty 2) Agilent 87206B 

SP6T Switches

• (qty 8) Agilent N1810UL 

SPDT Switches

Select the quantity of distribu-
tion boards for the required
switches using the ordering
info below:

• Qty 2 Y1152A 

Distribution boards 
to control qty 2 
87206B switches. 

• Qty 1 Y1150A 

Distribution board 
to control qty 8 
N1810UL switches.  

Notice that each Y1152A can
also drive two N181x switches.
Therefore if you only needed 
to drive 4 N1810 switches, 
then you could have controlled
those switches via the Y1152A
distribution boards already
selected.

Here is the final recommended
configuration:

• (qty 2) 87206B DC-20 GHz 

SP6T Switches

• (qty 8) N1810UL DC-20 GHz 

SPDT Switches

• (qty 1) L4445A 

Switch/Attenuator Driver 
(when ordering the L4445A, 
the 34945EXT is automatically
added for controlling switches)

• (qty 2) Y1152A 

Distribution Boards

• (qty1) Y1150A 

Distribution Board

• Either build own cables using 

off-the-shelf parts, or order 
qty 1 Y1159A 16-to-16 pin 
connect kit (supplies for 2 
cables) and qty 2 Y1157A 
9-to-10 pin cable kit 
(supplies for 4 cables).

We recommend that the switch
be ordered with options for 
24 V coils, position indicators,
and socket connectors. Since
24 V latching relays are speci-
fied, there is no need for an
external power supply. The
L4445A instrument can provide
power for a single 34945EXT.
Easy-to-build ribbon cables 
can be built to interface each
of the switches to the Y1150A
and Y1152A distribution boards.
See the Application note:
Configuring an RF/ Microwave
Switch System (5989-2272EN)
for additional configuration
details.
