New microwave power divider can handle 250W at frequencies up to 2.5GHz

New from Link Microtek is the Model 2372A-2 two-way power divider, which operates over microwave frequencies from 500MHz to 2.5GHz and can handle an input power of up to 250W CW or 2kW peak. Manufactured by Narda, the device can also be used as a non-coherent 125W-per-signal power combiner and is suitable for a variety of applications in telecommunications infrastructure.
It incorporates proprietary high-power, thin-film resistors to ensure broadband impedance matching and high isolation between inputs when used as a combiner. These resistors are directly attached to the housing to optimise thermal transfer so that the film temperature remains stable throughout the unit’s operating temperature range.

Featuring an insertion loss of less than 0.6dB, the 2372A-2 provides exceptional phase and amplitude balance of +/-5deg and +/-0.25dB respectively. VSWR is less than 1.5:1, and isolation is specified as at least 13dB up to 700MHz, rising to 18dB at 2.5GHz.

Employing N-type female connectors, the power divider is finished with tri-alloy plating and measures 88.9 x 63.5 x 25.4mm.
