Four-Way Dividers Cover 1 To 20 GHz

A pair of four-way Wilkinson power dividers from Marki Microwave provide total frequency coverage of 1 to 20 GHz. Model PD4-0218 operates from 2 to 18 GHz while model PD4-0120 spans 1 to 20 GHz. The model PD4-0218 four-way power divider minimizes insertion loss to typically 1.2 dB above the nominal splitting loss, with minimum isolation between ports of 15 dB and typical VSWR of 1.30:1. It features amplitude balance of 0.2 dB and phase balance of 2 deg. Model PD4-0120 has excess insertion loss above nominal power splitting losses of just 1.3 dB from 1.8 to 20.0 GHz and 1.6 dB from 1.0 to 1.8 GHz. The minimum isolation is 12 dB while typical VSWR is 1.60:1 or better at all frequencies. The 20-GHz divider delivers amplitude balance of 0.25 dB and phase balance of 3 deg. Both are supplied with SMA connectors.
