LPD
Power Dividers
LPD, MPD, PD, SPD Series

Power dividers are manufactured in a broad range of styles and types for varied applications. Generally a power divider consists of a junction block with a multi-stage quarter wave transforming section. Unequal power division may be achieved by adding quarter wave transforming sections between the junction block and the outputs.

Power dividers are available in 4 basic series:
LPD series - Low cost , low power equal split dividers using N type connectors.

MPD series - Low cost, low power equal split dividers (up to 4 way) using 7/8"" EIA input connectors and N type output connector.

PD series:
Used for most common applications with up to 8 way division with ratios of up to 7dB in almost any combination. Wideband performance with multistage transforming sections, 7/8"" EIA flanged input and EIA or DIN output connectors. Connectors are in-line to conserve space.

SPD series:
Similar to PD series but with up to 4 way split. EIA or IEC connectors, short circuit stub across the junction provides tuning and DC grounding. Additional low power arms are available where unequal power splits are required.
