Model 151-215-004 is a 50 Ω, 4-way resistive power divider with a DC – 6 GHz frequency range. This unit has a 1-Watt average power rating, 1.30:1 maximum VSWR, +/- 1.0 dB maximum insertion loss (above theoretical loss). The operating temperature range is -20° C to +100° C and the RF connectors are SMA female. This model was designed for a tactical radio application.
Resistive power dividers have inherent characteristics that make them an excellent choice for certain applications. These units are small, extremely broadband, and are the only type of power divider that operates DC onwards.
A resistive power divider has a power ratio of (1/N)2 (where N is the number of outputs) when compared to a reactive power divider which has a power ration of 1/N. This means for a 2-way divider with 1-Watt input power, a reactive unit’s output port will have 0.5-Watts (50% or 3 dB loss) of power on each port, while a resistive divider’s output will have 0.25-Watts (25% or 6 dB loss) of power on each port.
Resistive dividers loss includes distribution loss and inherent resistive loss, unlike the “lossless” reactive dividers (which only have distribution loss). Insertion loss of a resistive power divider is double that of a similar reactive unit. In a resistive power divider, insertion loss = isolation
BroadWave Technologies manufactures a wide variety of resistive power dividers in 2, 3, 4, 5, 6 and 8-way configurations. Available connector types are BNC, N, SMA and TNC or mixed connector types for unique applications. Resistive power dividers are ideal for commercial distributed antenna systems, military antenna sharing, test, and application that operate DC onwards.
