agilent 86205A & 86207a 50 ? & 75 ? rf bridges technical data 300 khz to 6 ghz (50 ? ) 300 khz to 3 ghz (75 ? ) 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. wide frequency range the bridges have an exceptionally wide rf frequency range: 300 khz to 6 ghz for the 50 ? 86205A and 300 khz to 3 ghz for the 75 ? 86207a. they are ideal acces- sories w hen used with the 8753 family of rf vector net- work 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 nor- mally associated with rf bridges. low insertion loss means more power to the de vice under test. this is required for the measurement of high-power solid state amplifiers and traveling wave tube amplifiers. flat coupling factor the frequency response of the coupled arm for t hese bridges is very flat, within 0.2 db of the nominal value of 16 db. this is important in appli cations 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. the 86205A/86207a high directivity rf bridges offer unparal- leled performance in a variety of general purpose applica- tions. they are ideal for accurate reflection measurements and signal-leveling applications. they com bine the directivity and broad-band frequency range of directional bridges and the low insertion loss and flat coupling factor of directional couplers.
