Agilent 86205A & 86207A
50 Ω & 75 Ω RF Bridges
Technical Data
300 kHz to 6 GHz (50 Ω)
300 kHz to 3 GHz (75 Ω)
The 86205A/86207A high directivity RF bridges offer
unparalleled performance in a variety of general purpose
applications. They are ideal for accurate reflection
measurements and signal-leveling applications. They
combine the directivity and broad-band frequency range
of directional bridges and the low insertion loss and flat
coupling factor of directional couplers.
40 dB directivity
Excellent directivity allows you to measure high return loss
devices and good port match lets you measure low return
loss devices. This is especially important when making
reflection measurements with scalar network analyzers,
vector network analyzers and spectrum analyzers.
Low insertion loss
These bridges offer low insertion loss, (nominally 1.5 dB),
which is significantly less than the typical 6 to 8 dB
normally associated with RF bridges. Low insertion loss
means more power to the device under test. This is
required for the measurement of high-power solid state
amplifiers and traveling wave tube amplifiers.
Wide frequency range
Flat coupling factor
The bridges have an exceptionally wide RF frequency
range: 300 kHz to 6 GHz for the 50 Ω 86205A and 300 kHz
to 3 GHz for the 75 Ω 86207A. They are ideal accessories
when used with the 8753 family of RF vector network
analyzers.
The frequency response of the coupled arm for these
bridges is very flat, within ±0.2 dB of the nominal value of
16 dB. This is important in applications such as external
power leveling where a power meter or diode detector is
used to remotely level the output power from an RF source
and when measuring power level dependent devices such
as the LO input to a mixer or the RF input to an amplifier
during compression testing.
