Agilent 87300B,C,D and 87301B,C,D,E Directional Couplers 87310B Hybrid Coupler Product Overview Features and Description Product Applications * Compact size * Broadband up to 50 GHz * Excellent performance 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 signal 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 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. generator or sweeper provides a leveled signal at a particular point in the system (Figure 1). Agilent 8474B,C,E detectors offer excellent broad-band frequency response and low SWR for this application. Other applications include power monitoring with an 848X series power sensor connected 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).
