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.

Model 854-252-BLK is a 50 Ω inner DC Block with a 10 – 2000 MHz operating frequency range and 0.4 dB maximum insertion loss. The maximum VSWR is 1.35:1, the maximum voltage is 100 Vdc and the RF connectors are BNC female / BNC female. This model was designed to clean up Airband Radio interference issues.

DC Blocks allow RF to pass through a circuit with minimal interference while preventing DC from passing through the circuit. Applications include ground loop elimination, signal source modulation leakage suppression, system signal-to-noise ratio improvement, and test setup isolation. Inner DC Blocks are realized by placing a capacitor of varying capacitance in series with the center conductor. The required frequency range, voltage breakdown and desired insertion loss determine the capacitance value selected.

BroadWave Technologies offers DC Block solutions in 50 and 75 Ω impedances with a variety of standard RF connector combinations. Between series RF connector configurations are available upon request. Please contact us with your unique requirement for the appropriate model number.

Model 554-118-002 is a 50 Ω, 2-Watt average, DC-3 GHz termination with a BNC male connector and beadchain. This termination exhibits 1.30:1 maximum VSWR (1.20:1 maximum VSWR up to 2 GHz) with an operating temperature range of -55℃ to +100℃. Originally designed as a calibration standard for a commercial application, these terminations are appropriate for aerospace and defense systems as well as laboratory test environments. Other connector types and average power terminations are also available. Please contact us with your unique requirement for the appropriate model number.
