GENERAL SPECIFICATIONS
Coupling, theoretical: -- 4.8 dB nom.
1. The PDG-3B series of 3-way Power Dividers/ Combiners covers 1 to 1000
MHz using lumped element circuits to minimize size while providing high
performance. The surface mount housing is suited to applications where
inherent package reliability and hermeticity are critical. All units are fully welded.
Impedance:
50 W nom.
Internal Load Dissipation:
50 mW max.
CW Input Power :
1 Watt max.
(When used as divider with 1.2:0 VSWRout
)
Operating Temp. Range:
-- 55° to + 85°C
