## Description

The Merrimac Industries PDM-20-250 is a space-qualified, 2-way in-phase power divider/combiner designed for RF and microwave applications. It operates across a wide frequency range of 10 to 500 MHz, offering a minimum isolation of 25 dB and a maximum VSWR of 1.3:1.

This device utilizes a lumped circuit technology, ensuring high performance characteristics such as low insertion loss (0.5 dB typical from 10-400 MHz) and precise amplitude and phase balance (0.2 dB and 2° maximum, respectively). The impedance is a standard 50 OHM, and it can handle up to 1 W of CW input power with a load VSWR of 1.2:1.

The PDM-20-250 is built to withstand demanding environmental conditions, with an operating temperature range of -55°C to +85°C. Its compact design, weighing only 28 grams, makes it suitable for space-constrained applications. This power divider/combiner is designed in accordance with Merrimac document CENG-0001, "Standard Design Requirements for Space Qualified Devices."
