Product Overview
Features and
Description
• Compact size
• Broadband up to 50 GHz
• Excellent performance
The Agilent Technologies 87300 series
of compact, broadband directional/
sampling and hybrid couplers are well
suited for signal monitoring or, when
combined with a coaxial detector,
signal leveling. See page 2 for the
wide range of product offerings.
Product Applications
These compact, broadband directional
couplers are important components
for many microwave measurement
systems. Although most modern signal
generators and sweepers supply signals
whose power levels are stable with
respect to frequency, variations in sig-
nal level are introduced due to the cable
losses (which increase with frequency)
and the frequency response of other
components in the signal path. Inserting
a directional coupler into the system
with a suitable microwave detector to
supply feedback to the ALC circuit of a
signal generator or sweeper provides a
leveled signal at a particular point in
the system (Figure 1).
Agilent 8474B,C,E detectors offer excel-
lent broad-band frequency response
and low SWR for this application. Other
applications include power monitoring
with an 848X series power sensor con-
nected to the sampling port. Connect
the sampled signal port to a microwave
counter to monitor frequency or to a
signal analyzer for frequency spectrum
monitoring (Figure 2).
