Bridge Features
– Frequency range from 300kHz to 6 GHz
– High directivity
– Insertion loss of 1.5 dB (nominal)
– Coupled arm flatness of ±0.2 dB from nominal
86205A operates over an RF frequency range of 300 kHz to 6 GHz and has excellent directivity for
high quality reflection measurements. Additionally, the bridge has a very low insertion loss of
1.5 dB which means more power to the device under test; this is especially important in the
measurement of high power solid state amplifiers and TWTs. The bridge also features a ±0.2 dB
flatness from the nominal 16 dB coupled arm. This capability is valuable in external leveling
applications where a power meter or diode detector is used to level the power remotely from the
source. Power variations are then minimized, which is important when measuring input-sensitive
devices.
DC bias may be applied to a DUT through the main arm of the bridge. (
DO NOT apply bias to the
coupled port of the bridge.)
Threaded mounting holes (3.5 mm x 0.5 mm) are located under pre-punched holes in the model
number label, as shown in Figure 2-2 . Since the bridge package is brass, appropriate caution must
be taken to avoid damaging the threaded holes.
