ORBIT/FR offers a complete line of pulse
modulators covering the frequency range from
0.1 to 110 GHz. The FR8305 Series covers 18 to
110 GHz. Each product is designed to use your
existing receiver and sources. The FR8305
Series provides the excellent sensitivity that is
critical for minimizing the required amounts of
averaging and reducing test times.
For Frequencies from 18 to 40 GHz
To cover the 18 to 26.5 and 26.5 to 40 GHz
bands, ORBIT/FR offers the FR8305A/K and
FR8305B/Ka, respectively. Each of these units
are self-contained, fully integrated down-
converters, up-converters, and pulse modulators.
No external frequency converter is required with
either of these two units. You can even use your
existing RF synthesizer, even if it only operates
to 20 GHz. These units require a second
synthesizer to serve as the LO source. The low
cost Agilent 83621A functions well as the LO
source. The output of these pulse modulators is
the 20 MHz IF required by the Agilent 8510BC
Network Analyzer or Agilent 8530A Microwave
Receiver.These units are efficiently packaged in
a single 5.25" high standard EIA chassis capable
of shelf-top or rack mount installations. A
waveguide interface to a quasi-monostatic radar
antenna configuration is provided at the rear
panel in the standard configuration. An optional
monostatic waveguide configuration or optional
2.9 mm coaxial antenna interface is also
available. Type 'N' IF jacks are also provided on
the rear panel for both the Transmit Reference
and Receive Test IF channels. These channels
are connected directly to the Agilent
8510C/8530A
For Frequencies from 40 to 110 GHz
ORBIT/FR also offers a line of Pulse Modulators
for operation at the higher millimeter-wave
frequencies. Bandwidths as wide as 10 percent
are supported with output power levels designed
to requirements. As with the FR8305A/K and
FR8305B/Ka modulators, each of the high band
units are self-contained, fully integrated down-
converters, up-converters, and pulse modulators.
No external frequency converter is required.
These units are compactly packaged in two
single 5.25" high standard EIA chassis (RFU &
PSU) capable of shelf-top or rack mount
installations. A waveguide interface to a quasi-
monostatic radar antenna configuration is
provided at the rear panel in the standard
configuration. · Higher power levels are
optionally available with decreased bandwidth.·
Broader bandwidths are optionally available.
