RSSNarda East Launches Two-Way Power Divider That Handles Up To 250 W
April 25, 2008
Hauppauge, NY – Narda, an L-3 Communications company, recently introduced the Model 2372A-2 high-power, two-way power divider that operates from 500 MHz to 2.5 GHz, handles up to 250 W CW input power (2 kW peak power), and provides exceptional phase and amplitude balance.
The Model 2372A-2 incorporates proprietary high-power, thin-film resistors that ensure broadband impedance matching and high isolation between inputs when used as a combiner rather than a divider. These resistors are directly attached to the housing through the use of spreading pedestals that optimize thermal transfer so the film temperature remains stable throughout the unit's range of operating temperatures. The resistor design and attachment scheme have also been optimized to present the least possible mismatch to the broadband circuit.
Other specifications of the Model 2372A-2 include insertion loss of less than 0.6 dB, amplitude balance of +/0.25 dB or less, phase balance of +/-5 deg., isolation of at least 13 dB to 700 MHz and 18 dB to 2.5 GHz, and VSWR of less than 1.5:1. The 2372A-2 employs Type N connectors and measures 3.5 in. x 2.5 in. x 1 in.
