The Agilent 87421A and 87422A power supplies

are universal input, dc switching power supplies

designed to provide the bias voltages needed to

operate Agilent microwave system amplifiers.

These compact power supplies are ideal for inte-

gration into a system or for use on a benchtop.

The 2 meter dc bias cable permits the amplifier

to be remotely located, allowing it to be placed

out of the way or where space is not critical.

The 87421A is a 25 watt, ±12V dc power supply

designed to power the Agilent 83006A, 83017A,

83018A, and 87415A microwave system amplifiers.

A 2 meter cable is included for direct connection

to the amplifier.

The 87422A is a 90 watt, ±15V dc power supply

designed to power the Agilent 83020A microwave

system power amplifier. One additional ±12V dc

output is provided to power a preamp such as

the 83006A or 83017A.

Included with the power supply are the necessary

2 meter cables to connect to the amplifier.

The 87421A may also be used to provide bias volt-

ages for the Agilent 83440C high speed lightwave

converter. Using the 83440-60009 lightwave con-

verter power supply adapter, the 87421A becomes

a compact, convenient power supply for use with

the lightwave converter.
