Power Splitters & Dividers Model 1870A Broadband Resistive Power Splitter dc to 18.0 GHz 1 Watt (Matching), Precision N Connectors RoHS MAXIMUM INPUT SWR: Frequency (GHz) dc - 18 Maximum SWR 1.30 EXPRESS www.argosysales.com 800-542-4457 EQUIVALENT OUTPUT SWR (Port 2 & 3): Frequency (GHz) Features These resistive power splitters are intended for RF and wireless applications in which one of the two outputs is included in a leveling loop or is used as a reference in a ratio system, for the purpose of providing an output signal whose source impedance is essentially matched to 50Ω. Some examples are: o A dual channel insertion loss measuring system (ratio). o A parallel IF substitution insertion loss measuring system (ratio or ALC loop). o A precision power source (ratio or ALC loop). dc - 2 2-4 4-8 8 - 18 Maximum SWR 1.05 1.07 1.10 1.15 * When used in a leveling or ratio system. TEST DATA: Insertion Loss, SWR, and Tracking measurements performed across the frequency band. Test data available at additional cost. CONNECTORS: Type N female connectors per MIL-STD348 interface dimensions - mate nondestructively with MIL-C-39012 connectors. WEIGHT: Net 170 g (6 oz) PHYSICAL DIMENSIONS: Specifications NOMINAL IMPEDANCE: 50 Ω FREQUENCY RANGE: dc to 18.0 GHz INSERTION LOSS: 6 dB nominal, 7.5 dB maximum (Between Input and either output).
